Isolation Transformers are applied in the consumer, communications, computing, medical, industrial and automotive etc, Isolation transformers were applied to isolate signals between low voltage and high voltage circuits, provide voltage to gate drive circuitry along with turn-on and control IGBTs. Isolation transformers platform have through-hole and surface mount, the winding configurations and ratios are design based on actual application, the isolation voltage are from 500Vrms to 10kVrms or higher，and the safety insulation including functional, basic and reinforced.
