Design Advantages
In the direction of improving stability and robustness, our company's product design margins are generally higher than those in the market other manufacturers. The design margin of all core devices is greatly increased compared with other manufacturers.
The most important components are B, DC support capacitors and radiators. Our company has increased redundancy for these three main components: B is generally redundantly set at voltage times, current times, all equipment uses B from Infineon of Germany. Currently, manufacturers in the mainstream market set voltage redundancy of about % and current of about %, and basically use B.
Our company uses capacitors imported from Canada for DC support capacitors. The designed capacitors are . However, capacitors from common manufacturers in the market have large ripples.
The radiators used by our company have been verified by simulation and actual measurement, and have excellent heat dissipation capabilities. For ordinary factory temperature rises, the temperature rise is generally in degrees Celsius, while the actual measured temperature rise of most manufacturers is in degrees Celsius.
Our company does not use Party A's switch cabinet. It has its own double contactors inside, with complete upper and lower isolation. This is completely different from the practice and ideas of ordinary manufacturers who use single contactors and use superior switch cabinets in order to save costs.
Our company's software design uses the more advanced repetitive + closed-loop design ideas to ensure high performance while taking into account system stability. However, mainstream manufacturers in the market only use the simplest control algorithm, and the system response time is slow and the phase The difference is large, and the overall performance is relatively backward.
The company's stability control uses an algorithm that independently controls the DC side capacitor voltage of each module. The more mainstream total voltage control algorithm improves the system stability a lot. The DC voltage imbalance that is criticized on many sites does not occur in our company. Appear.

Advantages of production technology
B boards have all undergone full aging testing at degrees Celsius to ensure reliable on-site application.
All modules are assembled in the anti-static B center. The B mounting and B board mounting and transfer work is meticulous and conscientious, reaching international advanced process standards.
