Abstract: A power supply and a gate driver includes a power switching element to control current, a control circuit to output a control signal for opening or closing of the power switching element, and a gate drive circuit to open or close the power switching element in accordance with the control signal. The gate drive circuit includes a first inductive circuit connected to a supply voltage source, and a second inductive circuit connected to an input stage of the power switching element, and transfers electrical energy stored in the input stage of the power switching element, using the first and second inductive circuits. Accordingly, electrical energy supplied to the input stage of the power switching element during an ON state of the power switching element is again recovered during an OFF state of the power switching element.

Abstract translation: 电源和栅极驱动器包括用于控制电流的功率开关元件，输出用于打开或关闭功率开关元件的控制信号的控制电路，以及根据本发明的开关元件打开或关闭功率开关元件的栅极驱动电路 控制信号。 栅极驱动电路包括连接到电源电压源的第一感应电路和连接到功率开关元件的输入级的第二感应电路，并且使用第一电感电流传送存储在功率开关元件的输入级中的电能 和第二感应电路。 因此，在功率开关元件的断开状态期间，再次恢复在功率开关元件的导通状态期间供应到功率开关元件的输入级的电能。
