Abstract :
A novel DC-DC converter is proposed that provides two independently regulated DC outputs from a single DC voltage source using one power semiconductor switch. The operation is based on the use of a low-pass filter and a higher-frequency bandpass filter. The output voltage supplied from the low-pass filter is regulated by controlling the duty cycle of the switch, while the other output voltage is controlled by changing the switching frequency.<>
