Abstract
An isolated power supply circuit has a first reference ground, a second reference ground, a power source, a first receiving circuit, a second receiving circuit, a first inverter circuit, a second inverter circuit and an isolated conversion circuit. The first reference ground and the second reference ground are isolated from each other. The first receiving circuit is coupled to the first reference ground. The second receiving circuit is coupled to the second reference ground. The power source provides a first power signal for the first receiving circuit directly. The first inverter circuit and the second inverter circuit receive the first power signal and produce a first inverter signal and a second inverter signal. And the isolated conversion circuit outputs a second power signal to the second receiving circuit based on the first inverter signal and the second inverter signal.
