Patent DE-4041711-A1 (DE)
Inventor: HORNUNG FRIEDRICH DIPL ING
IPC: H02P25/14
Filed: 1990-12-24
Abstract: Proposed is a control circuit which can be used for the phase control of an electric motor running off an a.c. power supply. The ground terminal of the circuit is connected directly, together with the cathode of a semiconductor switch (triac), with the load circuit. Thus voltage-cut-off means are unnecessary if signals from the load circuit are fed directly to the control circuit. In order to ensure the correct functioning of the phase synchronization input, an auxiliary power supply is connected in between this input and the ground terminal.
