STAND-ALONE MATCHED INVERTER WITH RESONANT COMMUTATION Russian patent published in 2012 - IPC H02M7/5387 

FIELD: electricity.

SUBSTANCE: in the stand-alone matched inverter with resonant commutation containing connected to input pins of inverter via saturated-core reactors (1, 2) and magnetically coupled reactance coils (3, 4) of filter which are connected accordantly, one phase bridge on controlled gates (5-8) with opposite-parallel diodes (9-12), which gates are shunted by serial circuits consisting of capacitor (13-16) and resistor (17-20), direct current pins of bridge are shunted by filter capacitor (21) series circuit of two damping capacitors (22, 23) common point of which is connected to inverter body pin via damping resistor (24), alternating current pins of bridge are shunted by series circuit of protective capacitor (25) and protective resistor (26) and connected with output pins of inverter via series circuits of commutating inductors (27, 28) and limiting saturated-core reactors (29, 30), commutating inductors are magnetically coupled and connected accordantly, output pins of inverter are shunted by compensating capacitor (31). Load (3 2) is connected to output pins of inverter.

EFFECT: enlarging the application area of stand-alone matched inverter with resonant commutation.
