ABSTRACT:
The switching power supply has high output power, high efficiency and fixed or variable output voltage. The input voltage may be AC or DC. Preferably, the input current is constant. Smallest possible peak currents of switches result in best possible line and component utilizations at any time.
In one embodiment, a first converter has an output for converting DC input voltage into a base voltage. A first capacitor is coupled between the DC input voltage and first converter output for storing the base voltage. A second converter is coupled to the first converter output for determining the output voltage. A second capacitor filters the output voltage. Both converters are referenced to ground. A diode applies the DC input voltage to the output.
