ABSTRACT:
A frequency dependent controller utilizes a loosely coupled transformer, which controller is adapted to change the operating characteristics of the transformer by varying its operating frequency in accordance with the requirements of a load to be supplied with power. If the transformer is operated at a single frequency, the maximum current that can be delivered is limited by the reactance of the transformer. If the transformer is operated over a frequency range by the controller, the maximum current and other operating characteristics of the transformer are a function of both the magnetic shunt and its then current operating frequency. Frequency control of a loosely coupled transformer permits precision electronic regulation of the transformer's operating characteristics and is suitable for control of a variety of devices, such as gas discharge lamps, DC to DC converters, AC to DC power and high voltage supplies, motor control and variable heaters.
