摘要:
Disclosed are half bridge inverter unit and inverter thereof. The half bridge inverter unit includes an inverter controlling module and inductors. The inverter controlling module provides different connection modes based on different operation modes so that the inverter meets the requirement of wide input voltage range as it can work in either voltage step-up mode or voltage step-down mode. The mid-point voltage between the DC series capacitors connected in parallel with DC power supply can be balanced automatically by taking advantage of the grid voltage symmetry with regard to positive and negative half cycles. The inverter is of single stage structure. It has advantages of low power loss, low cost, high efficiency and reliability.
