Abstract
A power conversion device, an isolated driving circuit, and an isolated driving method are disclosed herein. The isolated driving circuit includes a control module, a transformer, a rectifying circuit, and a driving auxiliary circuit. The control module is configured to generate a first pulse width modulation (PWM) signal and a second PWM signal according to the output signal. The transformer is configured to receive the first and second pulse PWM signals to generate a first control signal. The rectifying circuit is configured to generate a second control signal according to the first control signal. The driving auxiliary circuit is configured to generate a driving control signal according to the second control signal to drive the at least one power switch.
