ABSTRACT:
The protection device of an electronic circuit is an electronic AC circuit protection device. The protection device has the characteristic of over-voltage protection, over-current protection, electronic switch, and soft start. Devices of the protection circuit are electronic box, electronic devices box, and power factor regulator that is designed in the structure of L.C. in parallel on the source side of the protection circuit. The protection circuit can be applied in switching power supply, electronic ballast, etc., electronic circuit devices. The main electrical electronic devices include Triac Thyristor, Silicon Controlled Rectifier, Phototriac Coupler and Photothyistor Coupler etc. The protection device has characteristic of standing surge current that solving the problem of life and reliability of electronic devices in now a day. The invention is a necessary protection device for electrical industrial.
