THREE PHASE Z-INVERTER Russian patent published in 2016 - IPC H02M7/42 H02M7/5387 H02M7/00 

FIELD: electricity.

SUBSTANCE: three phase Z-inverter comprising a bridge voltage inverter with pulse-width modulation and a step up impedance link containing the first inductance, its one end is the positive input of the three phase Z-inverter, and the second end is connected with a diode anode, the second inductance connected by one end to a diode cathode, and by the second end to the positive input of the bridge inverter, the first capacitor connected by a positive pole to the second end of the first inductance and the diode anode, and by a negative pole to the second end of the second inductance and positive input of the bridge voltage inverter, the second capacitor connected by a positive pole to the diode cathode, the collector of a power transistor and the first end of the second inductance, and by a negative pole to the negative input of the three phase Z-inverter connected with a negative input of the bridge voltage inverter, the third capacitor connected in parallel to the input of the three phase Z-inverter, and the third inductance connected by one end to the diode anode, and by the second end to the emitter of the power transistor.

EFFECT: limitation of the output voltage of the Z-inverter in an idle mode.
