The charging pile power supply can quickly charge electric vehicles with high current in a short time, increase the driving range, and have bidirectional charging function to support the SMART GRID function. In the circuit topology design of the charging pile, besides the VIENNA structure topology currently used in the market, another way is mainly based on the Totem pole circuit. The advent of the latest third-generation compounds such as silicon carbide (SiC) semiconductors allows the bridgeless totem pole design to be applied. In the later stage of the DC-DC conversion part, both isolated (such as LLC design) and non-isolated designs are adopted. Actron can provide various discrete components such as silicon-based (silicon) IGBT and silicon carbide (SiC) MOSFET, diode according to different customer design and cost considerations, adopting standard specifications design and having high stability to accelerate product promotion and time to market.
