A voltage regulator is provided that includes a plurality of buck-boost transformers each having primary and secondary windings. The secondary windings of the transformers are electrically disposed in series between a source and a load. Each transformer is controlled by a plurality of control switches configured to control the voltage across the primary winding of a corresponding transformer. A controller monitors the output voltage and generates control signals for the switches. The transformers generate different voltage level changes in between the source and load and the voltages across the primary windings are capable of assuming opposite polarities to enable scaling of resolution and range. The voltage regulator efficiently regulates power with relatively few or no moving parts and also partially protects the power switching components by removing them from the path of the load current thereby producing a device that is smaller in size, costs less and is more reliable.
