FIELD: electricity.
SUBSTANCE: invention relates to the field of power conversion equipment and is proposed to be used in service power supply sources of energy-intensive telecommunication and radio equipment. Result is ensured by eliminating voltage pulses and high-frequency oscillations at the output of the rectifier and the total voltage with phase-pulse modulation by closing overvoltage currents by introducing the first, second and third diodes into the converter, as well as an additional key power amplifier, a transformer, a capacitive divider and an additional driver, which is connected between the first direct and inverse outputs of the phase-pulse converter and the direct and inverse inputs of the additional key power amplifier.
EFFECT: reduction of energy losses at increase of reliability and improvement of electromagnetic compatibility indices.
