Controlling electricity supply to load

摘要

A load (CH) is supplied from a source (CA) and rectifier (REDR) through a switching unit (COM) and a filter (FILT). A supply voltage zero is detected (Do) and stored in memory (MEM) until replaced by a signal of a second event (Du,Di,DI,TEMP). The switching unit (COM) in the power circuit is controlled by the memory state through an interface (INT) and is closed on zero voltage detection and open on second event detection
