Abstract
An inverter device comprises a first stage circuit, a second stage circuit and a control module. The first stage circuit comprises a first switch module and a charge-discharge module. The second stage circuit comprises a second switch module and a filter module. The control module outputs a first control signal for controlling the first switch module to turn on/off and a second control signal for controlling the second switch module to turn on/off. The control module obtains an input current from the first stage circuit, and adjusts the input current according to a predetermined current value. In addition, the control module obtains an output power from the AC output terminal, and adjusts the duty cycle of the first control signal according to the output power and a predetermined output power.
