ON AND OFF CONTROLLED RESONANT DC-DC POWER CONVERTER Russian patent published in 2018 - IPC H02M3/337 H02M3/338 H02M7/523 

FIELD: electrical engineering.

SUBSTANCE: invention relates to the field of electrical engineering and can be used in resonant DC-DC converters. Resonant DC-DC power converter comprises an input side circuit comprising a positive and a negative input terminal for receiving an input voltage or current and an output side circuit comprising positive and negative output terminals for supply of a converter output voltage and connection to a converter load. Resonant DC-DC power converter further comprises a rectification circuit connected between an output of a resonant network and the output side circuit. Resonant network is configured for alternatingly being charged from the input voltage or current and discharged through the rectification circuit by a first controllable switch arrangement in accordance with a first switch control signal. Second controllable switch arrangement of the resonant DC-DC power converter is configured to select a first impedance characteristic of the resonant network in a first switch state and select a second impedance characteristic of the resonant network in a second switch state. Output voltage or current control circuit is configured to adjust the converter output voltage and/or current by activating and interrupting the first switch control signal in accordance with the switch state of the second controllable switch arrangement.

EFFECT: technical result is simplification while ensuring high quality of output voltage control of the converter.
