摘要： An inverter circuit includes a DC-AC inverter, a sampling circuit, a voltage-current conversion circuit, an isolation circuit and an electronic starter switch. The sampling circuit includes a first and a second diode connected in parallel and opposite in polarity. A forward voltage drop at the first diode blocks the conductance of a first transistor of the voltage-current conversion circuit when there is no load, and a forward voltage drop at the second diode turns on the first transistor when there is a load. The connection of the first and second diodes to a second AC output terminal of the DC-AC inverter nearly has no impact on the AC output of the inverter circuit. These enable the inverter circuit to have low power consumption when there is no load and to be immediately activated upon connection of a load, thereby achieving detection of a load smaller than 0.1 W.
