Title: Control method and system for three-phase grid-connected inverter, and three-phase grid-connected inverter
Inventor: WU JIAN
IPC: H02M7/5387
Filed: 2020-02-17
Abstract: A control method and control system for a three-phase grid-connected inverter, and a three-phase grid-connected inverter. The control method is applied to a three-phase three-bridge grid-connected inverter. By improving the structure of the three-phase three-bridge grid-connected inverter, filter capacitors (C1, C2, C3) are connected to the negative pole of a direct-current input bus to form a harmonic bypass channel so as to improve the ability to suppress harmonics, thereby achieving a high-quality grid-connected current at low power, such that there is no need to increase the inductance of inductors (L1, L2, L3), and accordingly, parallel inverter devices in a system can operate stably, thus facilitating the present application to photovoltaic micro-inverters. Moreover, the three-phase three-bridge grid-connected inverter works in a mode with discontinuous inductor currents (i  L1 , i  L2 , i  L3 ), that is, when power switches (Q  1 , Q  2 , Q  3 , Q  4 , Q  5 , Q  6 ) on bridges are turned on, the inductor currents (i  L1 , i  L2 , i  L3 ) drop to zero, so that the switching loss of power switch tubes (Q  1 , Q  2 , Q  3 , Q  4 , Q  5 , Q  6 ) is reduced, thereby improving the conversion efficiency of the inverter.
