具有自动电流平衡和零电压开关的非隔离双通道LED驱动器

In this paper, a nonisolated two-channel light-emitting diode (LED) driver with automatic current balance and zero-voltage switching (ZVS) is presented. In this LED driver, a dc-blocking capacitor is connected with one side of the coupled inductor. Therefore, based on the ampere-second balance, a current source is generated with the average value of the positive current identical to the absolute a...
