Multiple-Carrier Pulse Width Modulation for Inverter Operation

A method for generating pulse width modulated control signal has the steps of providing a base carrier waveform, segmenting the base carrier waveform into a plurality of...

Multiple-Input Buck Boost Power Converter

A power converter circuit to convert multiple direct current (dc) inputs to one or more dc outputs. This dc-dc power converter allows its load to be powered by multiple,...

Series-Input Parallel Output Multiple DC-DC Converter with Dynamic Current Sharing for High-Current DC Power Supply

The combination of a unique series-input parallel-output (SIPO) circuit configuration and a sensorless current mode (SCM) technique ensures automatic and nearly perfect...

Commutation technique for an ac-to-ac converter based on state machine control

This invention is a technique that resolves current commutation challenges in various types of ac-ac switching power converters. It also applies to inverters and...

String Protection for Photovoltaic Cells

Hot-spotting is a common problem in solar panel configurations that can potentially damage photovoltaic cells by forcing the conduction of reverse current in shaded or...

Trade-off Method for Power Factor Correction

The invention recognizes that filter size can be reduced substantially as power factor is permitted to deviate below unity in systematic ways. Preferred methods of the...
