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 storinginput line voltage to an inversely connected pair of thyristors when both the thyristorsare off. Stored voltage is provided via a power lead to each thyristor driver to providepower thereto and thus the circuit operates in a self-powered manner.
