摘要: A method and/or apparatus used with a thyristor based AC-AC motor controller in a discontinuous current mode for providing power to thyristor gate drivers. The apparatus includes a snubber network and two rechargeable capacitors for storing input line voltage to an inversely connected pair of thyristors when both the thyristors are off. Stored voltage is provided via a power lead to each thyristor driver to provide power thereto and thus the circuit operates in a self-powered manner.
