Abstract
A low voltage, low frequency multi-level power converter capable of power conversion is disclosed. The power converter may include a low voltage, low frequency circuit that includes a plurality of phase-shifting inverters in series; a plurality of low voltage source inputs, and a plurality of phase-shifting inverters in series. Each of the plurality of phase-shifting inverters may be configured to receive at least one of the plurality of low voltage source inputs; and generate at least one square wave output. A semi-sine wave output may be derived from the generated at least one square wave output.
Claims20
A photovoltaic power converter, comprising:
- a plurality of low voltage source inputs derived from the photovoltaic power;
- a plurality of phase-shifting inverters in series, each of the plurality of phase-shifting inverters being configured to:
- receive at least one of the plurality of low voltage source inputs, and
- generate at least one square wave output therefrom;
- at least one series voltage regulator coupled in series to one or more of the plurality of phase-shifting inverters suitable to secondarily smooth the at least one square wave output into a semi-sine wave output.
