摘要：A DC/DC converter, a power converter and a control method thereof aredisclosed, 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 acontrol 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 theload is a light-load or a no-load, the control unit controls ON/OFF state of the first andsecond switches by pulse width modulation mode to convert an input voltage into atleast one rectangular wave for the resonant tank. A duty ratio of the first switch is withina 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/DCconverter is greater than 1.
