DV/DT limiting of inverter output voltage

Invention: DV/DT limiting of inverter output voltage

Year    Description
1995Invention patented by David J. Gritter and Jeffrey A. Reichard on January 17th, 1995. Abstract: A voltage rise limiting circuit (10) for use in conjunction with an inverter-driven induction motor (14). The circuit (10) includes capacitors (C4, C5, C6) connected in a delta configuration, with each node (64, 66, 68) coupled between an inductor (L7,L8,L9) and an input line of a diode bridge rectifier. The rectifier clamps positive voltage levels, putting trapped energy back into the dc inverter bus.
