CONSTANT-TO-CONSTANT VOLTAGE CONVERTER WITH ISOLATION ON THE CAPACITORS Russian patent published in 2018 - IPC H02M1/16 H02M1/44 H02M3/137 H02M3/145 

FIELD: electrical equipment.

SUBSTANCE: invention relates to the field of electrical equipment, radio electronics and can be used in secondary power sources as a constant-to-constant voltage converter. Constant-to-constant voltage converter with insulation on the capacitors includes the converter positive and negative inputs, the input capacitor, the MIS transistor with the n-channel, the transformer, first and second isolation capacitors, rectifier diode, output capacitor, positive and negative outputs of the converter. Input capacitor first terminal is connected to the converter positive input, the input capacitor second lead is connected to the converter negative input. Transformer primary winding beginning is connected to the converter positive input, the transformer primary winding end is connected to the drain of the MIS-transistor with the n-channel, which gate is the input for the control signal U_con, which source is connected to the converter negative input. First insulating capacitor first terminal is connected to the end of the transformer primary winding. First insulating capacitor second terminal is connected to the anode of the rectifier diode, which cathode is connected to the converter positive output. Second insulating capacitor first output is connected to the converter negative input. Second insulating capacitor second terminal is connected to the converter negative output. Output capacitor terminals are connected between the converter positive and negative outputs. Beginning of the transformer secondary winding is connected to the converter negative output, the end of the transformer secondary winding is connected to the anode of the rectifier diode.

EFFECT: technical result consists in increasing of the efficiency, reducing the level of the output voltage ripple, increasing noise immunity, improving electromagnetic compatibility, increase in the safety during operation and servicing due to creation of galvanic isolation.
