Abstract:
The present invention provides a power limiting circuit for inverter device and an inverter device, which pertains to the technical field of power source inverting. The inverter device comprises a first logic judging circuit for comparing an input current of an inverter circuit with a first preset current threshold and outputting a first signal when said input current is larger than the first preset current threshold; and a shunt circuit for shunting a portion of the input current of the inverter circuit when receiving said first signal; wherein, the shunt circuit comprises a shunt resistance and a first controllable switch, the shunt resistance and the first controllable switch are connected in series and then parallel-connected to input ends of the inverter circuit, a control end of the first controllable switch is connected to an output end of the first logic judging circuit for controlling the first controllable switch to be connected when receiving said first signal. This circuit enables the inverter device to be directly loaded with an inductive load, while an industrial frequency transformer can be dispensed with, so that the weight of the inverter device is greatly reduced, which allows the inverter device to be easy to move and carry around.
