摘要：A PWM control circuit of a power converter includes an upper-bridge elementQ, connected to a lower-bridge element Q by a node, which activates by a driver Q and Qfor switching-on and switching-off; the driver is controlled by a PWM signal. The node
further connects to an output inductor and an output capacitor and controls the currentof the output inductor to charge the output capacitor to produce an output voltageVOUT. A virtual ripple current PWM circuit includes a DC reference voltage level unit, anintegrator-plus-DC bias voltage eliminator, a phase synthesizer, a dual reference voltagelevel generator, and a PWM generator.
