An inverter includes a pair of switching elements operated by control signals from a signal generator to take two-position action in the same phase or in opposite phases, and a coupling transformer to couple the control signals so that ON actions or ON and OFF actions of the switching elements are synchronized with each other more precisely than circuits of the past have been able to provide.
A DC/DC power converter 10 which avoids shoot-through current by employing an energy storage fly-back inductor 27 having two separate primary windings 28 and 29, one for current in each direction. The fly-back inductor 27 is located inside the switching bridge. In addition, a transformer 30 having two separate windings 42 and 44 is also employed. Thus, shoot-through is avoided and an extra switch for pulse width modulation is not required. In addition, the device does not apply a greater voltage than the line voltage to the switches and "holes" in the output current are not created so that less noise is generated by the device.
