N2 - In the case of contactless power transfer system with the electromagnetic induction, the coupling coefficient between the coils is reduced by the misalignment of the receiving coils. This results in reduction of the output voltage and the active power in the coils. To cope with this problem, an instantaneous current control method is applied to the PWM rectifier of a single-phase contactless power transformer system. The switching loss increases due to higher operating frequency. In this paper, PWM rectifier with the control method is operated with single-pulse PWM mode to reduce the switching losses. It is revealed by experimental tests over a power range of several tens of watts that the proposed control method is effective even if the PWM rectifier is operated with single-pulse mode.
