摘要： A DC/DC converter, a power converter and a control method thereof are disclosed, where the DC/DC converter includes an output circuit having a load, a rectangular wave generator having a bridge arm, a resonant tank, a detection unit and a control unit. The bridge arm includes a first and a second switches connected each other. The detection unit detects a signal related to a state of the load. When the state of the load is a light-load or a no-load, the control unit controls ON/OFF state of the first and second switches by pulse width modulation mode to convert an input voltage into at least one rectangular wave for the resonant tank. A duty ratio of the first switch is within a first or second predetermined range, and a duty ratio of the second switch is complementary to the duty ratio of the first switch, whereby a voltage gain of the DC/DC converter is greater than 1.

摘要： The DC/DC converter includes a power unit, an output detection unit, a control unit and a compensation unit. The output detection unit detects an output stage of the power unit. The control unit provides a driving signal based on the output stage for the power unit to control the operation of the power unit. When the power unit operates in an intermittent working mode, the compensation unit provides a compensation signal for the control unit, and the control unit adjusts the driving signal according to the compensation signal, so that during at least one duty cycle an output power of the power unit in the intermittent working mode is higher than an output power of the power unit at a switching moment from a normal mode (continuous working mode) to the intermittent working mode, thereby when the load is not changed, the average number of driving signals is reduced.
