The invention relates to a power processing technique and device wherein a tank circuit is excited at resonance, in association with two phase modulated high frequency link converters in an arrangement wherein control of the operation is easily achieved even with operation at resonance. The tank circuit is series resonant and is connected on the primary side of a transformer between two full bridge inverters and serves to control operation of the device even when operated at resonance. The technique finds special utility in power conversion applications.
