Title: Control of multi-phase inverter with compulsory commutation - using pulse checking logic ccts to control thyristors
Inventor: ALBRECHT ROLAND DIPL ING
IPC: H02M7/525
Filed: 1975-02-17
Abstract: Control impulses are achieved by brief interruptions in the inverter stage supply, and the present circuit replaces the solid state power switch between the rectifier and inverter with a logic control for the inverter firing. The required output impulse transmission is given by a generator which, when mixed with the output of the thyristor firing impulses generated by an oscillator and divided between the respective inverter phases by the firing controls, suppresses firing thus causing the necessary output interruptions. At the same time the thyristors connected to the d.c. positive are fired to aid voltage spike suppression.
