ABSTRACT:
A direct current power transducer for driving alternating current devices utilizes a discharge tube connected across a current source, the construction of the tube and characteristics of the source being such as to maintain endogenous pulsed abnormal gas discharge within the tube. The tube is capacitatively coupled to an external load including an alternating current device, typically an electric motor. Electric motors of the asynchronous induction or synchronous types are particularly suitable, but other alternating current devices may be used. By adjustments to the current source, the capacitance in parallel with the discharge tube, and connections to auxiliary electrodes, the pulse repetition frequency of the discharge may be adjusted, thus allowing variable speed control of types of alternating current motor not normally amenable to such control.
