DUAL INPUT RANGE POWER SUPPLY USING TWO SERIES OR PARALLEL CONNECTED CONVERTER SECTIONS WITH AUTOMATIC POWER BALANCING |
摘要 |
A power supply comprises a first power converter having respective input and output terminals, and a second power converter having respective input and output terminals. The output terminals of the first and second power converters are connected in series to provide a combined output voltage. A switch is connected to the input terminals of the first and second power converters. The switch has a first state by which the input terminals of the first and second power converters are connected in series, and a second state by which the input terminals of the first and second power converters are connected in parallel. A pulse width modulator (PWM) unit provides a drive signal to regulate current provided to the first and second power converters. A balance winding is coupled between the first and second power converters in order to share power between these two converters when their inputs are connected in series.
