TIMONTA pulse transformers have been specially developed control semi-conductors power electronics. Application possibilities numerous various deal mainly with triggering Thyristors, Triacs, power transistors IGBTs. most cases there suitable model available from balanced component series development dependable economical circuits. desired specifications archived through specifically selected materials well-developed winding technology, provide following advantages:
Electrical separation circuit power circuit, with high insulation rating least between primary secondary windings. Electrical separtion with high insulation rating least between secondary windings. Simple circuit layout, since there sufficient power available circuit. This makes special extra provision power supply side unnecessary. Small coupling capacitances between primary secondary windings limit transient feedback from power supply side control electronics. defined partial discharge voltage guarantees effectively unlimited serviceable life.
