device for the feeding of a load from a vexelstromskella

摘要

The controller has a main supply line (8, 9) connected to the load (4, 6). There is a primary ignition circuit (60) to which energy is supplied by the above line (8, 9). There are two parallel ignition switching circuits (40, 50), in series with the primary ignition circuit (60), and ignition devices (41, 51) in series with forced communication devices (18, 20) and primary thyristors (14, 16). The forced communication device (18, 20) and the primary thyristors (14, 16) are in parallel with commutation ignition switching circuits (40, 50) working in opposite senses. The load (4, 6) is in series with the commutation ignition switching circuits (40, 50), inserted between the load (4, 6) and the primary ignition circuit (60).
