ABSTRACT:
An improved capacitive drop power supply is provided for use in home appliances. The power supply circuit includes: a rectifier for converting an AC power source to a DC voltage; a current limiting capacitance interposed between the AC power source and the rectifier; a low voltage output stage and a higher voltage output stage. The low voltage output stage supplies DC voltage from the rectifier to a microcontroller residing in the home appliance. The higher voltage output stage is connected in series with the low voltage stage and supplies DC voltage to the higher voltage loads associated with the home appliance. To reduce power consumption, a shunt circuit path is connected in parallel across the higher voltage output stage which causes a phase shift in the AC power signal and thereby reduce real power consumption when a no load condition is placed on the output stage (e.g., during a standby operating condition of the home appliance).
