Abstract:
A supply voltage generating circuit for generating a supply voltage signal to supply the active elements of an AC-DC voltage converter. The supply voltage generating circuit has a charging switch, a charging diode and a charging capacitor. When a main switch of the AC-DC voltage converter is turned on, the charging switch is turned on. Primary current flows through the charging switch and the main switch to the logic ground. When the main switch is turned off and the voltage across the charging capacitor is smaller than a charging threshold, the charging switch is kept on for a period of time and the primary current flows through the charging switch and the charging diode to the charging capacitor. When the period of time is expired or the supply voltage signal is larger than the charging threshold signal, the charging switch is turned off.

Claim (Index 6):
The supply voltage generating circuit of  claim 4 , wherein the charging time setting circuit comprises:\n an error amplifying circuit, having a first input terminal configured to receive the supply voltage signal, a second input terminal configured to receive the charging threshold signal, and an output terminal, wherein the error amplifying circuit is configured to compare the supply voltage signal with the charging threshold signal to generate an error signal at the output terminal of the error amplifying circuit; a ramp generator, configured to receive the main control signal, wherein when the main control signal is in the inactive state, the ramp generator configured to start to operate to provide a ramp signal; a second comparing circuit, having a first input terminal configured to receive the error signal, a second input terminal configured to receive the ramp signal, and an output terminal, wherein the second comparing circuit is configured to compare the error signal with the ramp signal to generate a second comparing signal at the output terminal of the second comparing circuit; and a second logic circuit, configured to receive the second comparing signal and the main control signal, and further configured to conduct a logic operation to the second comparing signal and the main control signal to generate the charging time signal.
