Electric car charger is a charging device specially configured for electric bicycle batteries, commonly used switching power type charger is divided into half bridge type and single excitation type two categories, single excitation type is divided into forward and flyback type two categories. The half-bridge type has high cost and good performance, and is often used in chargers with negative pulse; Single excitation cost is low, the market share is high, the current market chargers are mostly flyback.

The Super-Junction series features faster switching speeds, lower on-off losses, and extremely low gate charge (Qg), which reduces device power losses and improves system efficiency. Because of the use of independent innovation technology, the switching characteristics of the device are optimized, and the device has better EMI performance in the system. At the same time, Xinjie superjunction MOSFET has good robustness and is a high-efficiency and high-reliability solution for chargers.
