DC-to-AC power inverter and methods

An inverter comprising:

• one or more terminals configured to receive an input voltage signal;
• a first switching-mode signal generator coupled to the one or more terminals and configured to generate a first portion of an output voltage signal in a first mode;
• a second switching-mode signal generator coupled to the one or more terminals and configured to generate a second portion of the output voltage signal in a second mode;
• and
• an inverter controller coupled to the first switching-mode signal generator and the second switching-mode signal generator, the inverter controller being configured to operate the second switching-mode signal generator as a short-circuit path in the first mode and operate the first switching-mode signal generator as another short-circuit path in the second mode.

An inverter comprising:

• input terminals configured to receive a direct current (“DC”) signal;
• a modulator including subsets of modulator MOSFET devices configured to convert a DC signal into a first variable signal;
• transformers configured to convert the first variable signal to form a first portion of a second variable signal during a first interval, and to form a second portion of the second variable signal during a second interval;
• a waveform generator including subsets of waveform generator MOSFET devices configured to synchronize the first portion and the second portion of the second variable signal to a range of frequencies to generate an alternating current (“AC”) signal;
• output terminals;
• and
• an inverter controller configured to couple the input terminals via a first subset of the modulator MOSFET devices to a first transformer of the transformers and to decouple the input terminals from a second transformer of the transformers using a second subset of the modulator MOSFET devices during one interval of the first or second intervals, the inverter controller being configured further to couple the first transformer via a first subset of waveform generator MOSFET devices to a first output terminal of the output terminals and to couple a second output terminal of the output terminals via a second subset of waveform generator MOSFET devices to a reference potential during the one interval.
