Abstract

A rectifier circuit includes first and second load terminals, a first semiconductor device having a load path and configured to receive a drive signal, and a plurality of second semiconductor devices each having a load path and each configured to receive a drive signal. The load paths of the second semiconductor devices are connected in series, and connected in series to the load path of the first semiconductor device. A series circuit with the first semiconductor device and the second semiconductor devices is connected between the load terminals. Each of the second semiconductor devices is configured to receive as a drive voltage either a load-path voltage of at least one of the second semiconductor devices, or a load-path of at least the first semiconductor device. The first semiconductor device is configured to receive as a drive voltage a load-path-voltage of at least one of the second semiconductor devices.

Description

[0001] priority statement [0002] This application claims priority to US Patent Application Nos. 13 / 546,510 and 13 / 834,700, filed July 11, 2012, the entire contents of which are incorporated herein by reference. technical field [0003] Embodiments of the present invention relate to circuit configurations with rectifiers. Background technique [0004] A rectifier is an electronic circuit or electronic device that allows electrical current to flow in a first direction while preventing electrical current from flowing in an opposite second direction. Such rectifiers are widely used in various electronic circuits in automotive, industrial and consumer applications, especially in power conversion and drive applications. [0005] Conventional rectifiers can be implemented with diodes, which conduct current when forward biased and block when reverse biased. However, diodes incur relatively high losses when forward biased. These losses are proportional to the current through the...
