Circuit for converting an AC voltage into a DC voltage
Abstract
Circuit for converting an AC voltage to a DC voltage, wherein a full-bridge rectifier is replaced by two controlled switches. It is preceded by a throttle, so that the rectification function is also a power factor correction allows. The circuit has a center voltage at the output. As a result, with the help of two other switches, a rectangular load current can be generated.
