Abstract
A converter and a control method of sending a pulse width modulation (PWM) driver gating signal thereof. When an alternating current voltage output by the converter is in an O area, the converter may be controlled to switch between an upper half-bridge arm straight-through mode and a lower half-bridge arm straight-through mode. In this way, it can be ensured that there is a freewheeling path for a current in an inductive component, and a problem that a switching transistor of a secondary-side circuit is in a straight-through state is avoided.
