Abstract
The present invention discloses a low-cost voltage regulator circuit which provides at its output port, from one power source, a voltage of a set of different voltages to a load of electrical energy consuming devices, without power interruption to the load during transition time. The voltage regulator circuit includes a set of relays and a set of step-down transformers. Each of the relays receives a corresponding control signal, the magnitude of which is regulated to control the state of the associated relay. Each of the step-down transformers comprises a primary winding and a secondary winding. The secondary windings of the step-down transformers are connected in series between the positive terminal of the power source and the positive terminal of the output port, while each of the primary windings is coupled to the power source via an associated relay. Each pair of primary winding and secondary winding has a predetermined turns ratio and predetermined polarities to contribute a predetermined secondary winding voltage to the voltage across the output port.
