Abstract
A voltage regulator using a saturable transformer comprises a transformer having a primary and secondary windings, an AC power source for supplying the primary winding a fluctuating alternating current, and a rectifier connected to the secondary winding for rectifying an AC voltage derived therefrom to produce a DC output voltage. The transformer includes a core having four legs and two common portions magnetically joining the four legs, and a control winding supplied with DC control bias from a control circuit. The primary and secondary windings are wound on the first and second legs and the control winding is wound on the first and third legs.
Claims5
A voltage regulator using a saturable transformer comprising:
- a transformer including a ferromagnetic core having fours legs and two common portions magnetically joining said four legs, a primary winding wound on said first and fourth legs of said core, a secondary winding wound on said second and third legs of said core and a control winding wound on said first and second legs of said core such that no alternating flux is transferred from said primary winding to said control winding;
- an AC power source for supplying said primary winding a fluctuating alternating current;
- rectifier means connected to said secondary winding for rectifying an AC voltage derived therefrom to produce a DC output voltage;
- and
- control means including an error detector for detecting a deviation of said output voltage from a desired voltage and bias means for supplying a DC control bias to said control winding in response to a signal from said error detector.
A voltage regulator using a saturable transformer comprising:
- a transformer including a first and a second C cores, said first C core being rotated approximately 90.degree. with respect to said second C core, a primary and a secondary winding wound on said first C core and a control winding being wound on said second C core;
- an AC power source for supplying said primary winding a fluctuating alternating current;
- rectifier means connected to said secondary winding for rectifying an AC voltage derived therefrom to produce a DC output voltage;
- and
- control means including an error detector for detecting a deviation of said output voltage from a desired voltage and bias means for supplying a DC control bias to said control winding in response to a signal from said error detector.
