Analysis of ferroresonant type DC power supply controlled by fully magnetic technique

A high-frequency magnetically controlled ferroresonant-type DC power supply is presented. The resonant voltage is controlled by applying a external field through an electromagnet to the resonating reactor core in a diametrical direction. The voltage drop on the DDC side of the power supply is compensated for by feeding the output current back to the winding of the electromagnet. Static and dynamic characteristics of the supply are analyzed by using a control loop diagram. A theoretical criterion resulting in zero voltage regulation is established on the basis of the control loop diagram.<
