Abstract
In an electric power converter for a vehicle which is connected to an alternating-current generator for a vehicle and performs synchronous rectification, switching mistakes are reduced and efficiency is improved by setting an optimal control allowance time in generating a switching timing signal from a diode ON signal. A control allowance according to the operating state of a generator can be determined by obtaining a control allowance time as a sum of a control delay time which is constant irrespective of the operating state of the generator, and an allowance time which varies depending on the operating state of the generator. Thereby, optimal switching timing is obtained and the reduction of switching mistakes and an improvement in efficiency are performed.
