Title: Innovations by Peter Dähler in Power Electronics
Introduction
Peter Dähler is a notable inventor based in Remigen, Switzerland. He has made significant contributions to the field of power electronics, holding 2 patents that showcase his innovative approach to addressing mains system disturbances and voltage reductions.
Latest Patents
One of his latest patents is a power-electronic circuit arrangement designed for compensating mains system disturbances and voltage reductions. This invention features a second auxiliary voltage source, which operates at a lower voltage than the first auxiliary source. The circuit can function in two modes: one where the first auxiliary voltage source compensates for significant mains failures, and another where the second source is used for less severe disturbances, minimizing switching losses. This regulated mode allows for effective compensation while maintaining acceptable levels of switching losses in the semiconductor switches.
Another significant invention by Dähler is an invertor that consists of multiple invertor bridges operating in parallel. The output voltages of these bridges are summed, and they are driven using pulse duration modulation based on an auxiliary control voltage. The design includes a constant phase difference between the control voltages of the individual bridges, effectively suppressing common-mode current distortion through a strategically placed switch in the ground connection.
