Beschreibung
Zusammenfassung:	A high power supply relates to the technical field of a power supply. The circuit of the high power supply comprises a reverse excitation circuit and a high-voltage resonance circuit, the high-voltage resonance circuit comprises a high-voltage resonance half-bridge circuit and a power factor correction circuit, the reverse excitation circuit comprises a first rectifier bridge, the power factor correction circuit comprises a second rectifier bridge, and the first rectifier bridge and the second rectifier bridge use a power ground in common. A current limit resistor is provided, and the first rectifier bridge uses the power ground in common with the second rectifier bridge via the current limit resistor, so, when a large load is applied to the high-voltage resonance circuit, the temperature rise of the first rectifier bridge of the reverse excitation circuit can be effectively reduced, and the first rectifier bridge can be protected well.
