Abstract
An apparatus having a rectifier topology for use on a three-phase electrical system is disclosed. The apparatus includes an input filter at each phase, a rectifier set at each phase in power communication with and downstream of each respective input filter, and a separate and independent booster section at each phase in power communication with and downstream of each respective rectifier set. Each booster section comprises two switches, thereby providing a six-switch three-level discontinuous conduction mode (DCM) boost rectifier.

An apparatus having a rectifier topology for use on a three-phase electrical system, the apparatus comprising:
- an input filter at each phase;
- a rectifier set at each phase in power communication with and downstream of each respective input filter;
- and
- a separate and independent booster section at each phase in power communication with and downstream of each respective rectifier set;
- wherein each booster section comprises two switches, thereby providing a six-switch three-level discontinuous conduction mode (DCM) boost rectifier.
An apparatus for rectifying and boosting three-phase electrical power, the apparatus comprising:
- an input circuit and an output circuit;
- the input circuit configured for receiving three-phase ac voltage, and for delivering three-phase rectified voltage;
- the output circuit configured for receiving the three-phase rectified voltage, individually boosting the voltage of each rectified phase, and delivering boosted dc voltage to a first and second output terminal.
A method for providing three level dc voltage, comprising:
- receiving filtered and rectified three-phase ac voltage;
- and
- boosting individually the rectified voltage of each phase and combining the boosted voltage to provide three level dc voltage output.
