Introduction

Manuel Vetterli is a notable inventor based in Basel, Switzerland. He has made significant contributions to the field of power electronics, holding 2 patents that showcase his innovative approaches to electrical power conversion systems.

Latest Patents

One of his latest patents is a method for operating a power electronic converter device with floating cells. This invention describes a method of operating a power electronic converter device that includes a converter circuit with an input side, an output side, a first converter, and at least one second converter. The second converter features at least one floating cell with a DC intermediate circuit and semiconductor devices. The method involves switching the semiconductor devices of the floating cell at optimized pulse patterns or carrier-based pulse width modulation. It also includes determining a fundamental voltage component for the floating cell and generating this component in the actual voltage of the floating cell by modifying the switching instants. This ensures that the voltage of the DC intermediate circuit lies within a specified reference voltage range for balancing purposes.

Another significant patent by Vetterli focuses on detecting shorted diodes. This invention includes a method, a controller unit for a bridge rectifier, and a bridge rectifier system designed to detect a shorted diode. The method determines a phase-to-phase voltage between two phase inputs of the bridge rectifier and indicates a shorted diode fault by checking if the phase-to-phase voltage remains zero for more than the commutation time of the bridge rectifier.
