Beijing, China (November 12, 2024) - Leading semiconductor device supplier GigaDevice (stock code 603986) held a new product launch event in Shanghai today with the theme of "Brave Leap? Chip Journey". Industry partners from industries such as industrial and digital energy gathered together to celebrate the occasion. At this press conference, Zhaoyi Innovation showcased its latest achievements in industrial automation, digital energy, and other fields. It not only unveiled two new MCU products - EtherCAT slave control chip and GD32G5 series Cortex-M33 core high-performance MCU, but also simultaneously launched a series of motor control and digital energy solutions equipped with new MCU products. At the same time, many partners also launched innovative solutions based on GD32 MCU for the first time at the press conference. This not only demonstrates the continuous attention and firm commitment of Zhaoyi Innovation in the industrial and digital energy fields, but also reflects the close cooperative relationship and solid market foundation between the company and industry partners.

EtherCAT servo slave solution helps improve industrial control intelligence efficiency

In the development process of Industry 4.0, the manufacturing industry is steadily moving towards intelligence, networking, and automation, and the demand for efficient and reliable communication technology is becoming increasingly urgent. EtherCAT (Ethernet for Control Automation Technology), as a real-time industrial fieldbus communication protocol based on Ethernet, can provide nanosecond level precise synchronization, which is crucial for servo drive systems. Servo drive systems typically require precise coordination of the actions of each axis, and EtherCAT ensures that each servo axis synchronously receives and executes control instructions in a very short period of time, thereby achieving fast and accurate synchronous motion of multi axis servo drives, thereby improving production efficiency and optimizing mechanical performance.

The servo slave system solution launched by Zhaoyi Innovation is mainly controlled by the GD32H75E series ultra-high performance industrial interconnect MCU with Cortex-M7 core, and integrates the ESC (EtherCAT SubDevice Controller) module. The system adopts the standard CIA402 protocol and is controlled in real-time through TwinCAT. The solution supports various working modes such as contour position mode (PP), 30 origin regression modes (HM), and cyclic synchronous position mode (CSP). The built-in HPDF module and external sigma delta modulator enable in line current sampling, which not only improves motor control performance but also ensures reliability and stability under complex operating conditions. This solution can be widely applied in application fields such as CNC lathes, robots, automated production lines, and robotic arms.

3.5kW DC charging station and portable bidirectional energy storage solution help optimize energy efficiency

With the transformation of the global energy structure and the rapid development of the new energy vehicle market, the digital energy industry has ushered in a new era of rapid development. In this context, Zhaoyi Innovation has launched a 3.5kW DC charging pile and portable bidirectional energy storage inverter solution based on the GD32G5 series high-performance MCU to meet the urgent market demand for efficient, intelligent, and environmentally friendly energy use.

As the control brain of DC charging stations, MCU can accurately regulate the output of charging stations, convert grid voltage into DC voltage, charge new energy electric vehicles, and ensure the efficiency and safety of the charging process. The 3.5kW DC charging pile solution based on GD32G5 series high-performance MCU launched by Zhaoyi Innovation adopts a single MCU chip to control a two-stage topology (front stage single-phase totem pole PFC and rear stage full bridge LLC), where the switching frequency of PFC is 70kHz and the switching frequency of LLC is 94kHz~300kHz. The input voltage of the scheme is 220V (± 10%)/50Hz, and the maximum effective value of the input current is 17A; The output voltage is 250VDC~450VDC, supporting trickle, constant current, and constant voltage charging. The scheme achieves a peak efficiency of 96.2%, PF of 0.999, and THD of 2.7%, which can meet the stringent requirements of current electric vehicle charging applications.

At the same time, Zhaoyi Innovation has also launched a portable bidirectional energy storage inverter solution. The plan uses AC power from the power grid to charge the battery, in order to output the stored electrical energy to supply electrical equipment during power outages or outdoor scenarios. For this solution, users can choose to use the new GD32G5 series high-performance MCU or GD32E5 series MCU as the main control unit. The scheme consists of two MCUs controlling a three-level architecture, including LLC, Buck/Boost, and inverter/PFC. Among them, the switching frequency of LLC is 100kHz, and the switching frequency of Boost/Buck and inverter/PFC are both 20kHz. In grid connected charging mode, the solution can convert 220VAC mains voltage into 24V DC voltage for constant current or constant voltage charging of the battery pack, with a maximum power of 500W; In off grid power supply mode, the battery voltage of 20-27.2V can be inverted to 220VAC mains voltage, with a maximum power of 1kW. This solution can be widely applied to various scenarios such as outdoor camping, aerial photography, mobile office, emergency charging, emergency disaster relief, medical rescue, etc.

In addition, key solutions from Zhaoyi Innovation in areas such as GUI graphic display, AI, wireless connectivity, information security, and functional security are also showcased simultaneously. Zhaoyi Innovation has been rooted in the industrial and digital energy markets for many years. With its rich product categories, enhanced processing efficiency, and diverse resources, it can continue to provide support for market applications. Diversified and comprehensive industry solutions are a one-stop solution to meet customer needs, helping customers achieve agile development.

Joining hands with industry partners, numerous innovative solutions are presented brilliantly

At this press conference, multiple partners of Zhaoyi Innovation also simultaneously launched a new solution based on GD32 MCU. Among them, Shenzhen Zhongdian Port Technology Co., Ltd. has brought a commercial and industrial energy storage BMS solution based on GD32F527/GD32VW553. This solution is technologically advanced, fully functional, safe and reliable, using automatic address addressing technology. The architecture is flexible and scalable, supporting multiple upgrade methods locally or in the cloud. Through algorithms, the battery intelligent balancing strategy can be flexibly adjusted according to different operating states. The scheme is equipped with multi-level fault protection mechanism and two-level data storage mechanism, which can ensure the stable operation of the system and the security of data. Based on this solution, customers can also carry out secondary development according to their specific needs. This high degree of flexibility greatly reduces development time and is expected to save customers at least six months of development cycle. The solution covers a wide range of application scenarios, whether it is large-scale energy storage systems such as photovoltaic energy storage, wind energy storage, base station energy storage, or small energy storage devices such as home energy storage, portable energy storage, vehicle energy storage, UPS, etc., they can all be perfectly adapted.

At the same time, Nanwei Semiconductor, a partner of Zhaoyi Innovation, has launched a new CRPS185 4.5kW AI data center server power solution. This solution relies on the innovative GD32G553 high-performance MCU from Zhaoyi, as well as the nano micro GaNSafe? High power gallium nitride power chip, GeneSiC? The third-generation fast silicon carbide power device exhibits excellent performance with an ultra-high power density of 137W/in3 and an efficiency of over 97%. The scheme adopts a two-stage scheme of interleaved parallel totem pole PFC and high-frequency full bridge LLC. Among them, the interleaved parallel totem pole PFC can achieve excellent digital control by being equipped with the LQFP48 GD32G553CET7 model; The 300kHz high-frequency full bridge LLC adopts the LQFP128 GD32G553QET7 model, which not only enables precise control of the high-frequency LLC, but also enables timing control of the power supply and communication with I2C/PMbus.
