THICK-FILM VOLTAGE REGULATOR FOR THREE-PHASE ALTERNATORS

摘要

Improvements in regulators for three-phase current generators, especially for vehicles, which adjust the voltage delivered by the generator to the theoretical value, controlling the flow of current through the excitation winding and consisting of electronic elements such as transistors, diodes, resistors and capacitors, which are connected to each other and incorporated in a box, characterized in that the box consists of material with good thermal conductivity and is provided with cooling fins for heat evacuation, holes for the connecting wires and external fixing means, for that the electronic regulation circuit is made as a thick-layer hybrid circuit on an insulating substrate with connection bands and oven-dried resistors and with subsequently soldered capacitors and semiconductors, because a Zener didod is arranged next to the insulating circuit substrate as protection against the s Overstension, which is mounted on a separate metal substrate plate and so that the two substrates are fixed with a glue of good thermal conduction on the underside of the box.
