Abstract:
A voltage control apparatus for controlling voltage delivered to a load, said apparatus comprising:a transformer including primary connections to connect to a source of power at an input voltage, and including a plurality of output connections, said transformer being configured to present a plurality of secondary voltages at said output connections in response to input voltage;a connection circuit coupled with said transformer and configured to couple said transformer with a load so as to provide one of a buck or a boost in voltage delivered to said load, said connection circuit including a plurality of selectable, actuatable connection elements operable to interconnect selected ones of said output connections with said load; anda control circuit coupled with said connection circuit and coupled with said transformer to sense one of said voltages as a reference voltage and responsive thereto to actuate selected ones of said connection elements to produce a selected output voltage from said secondary voltages including one of a buck or a boost of said input voltage for delivery to a load.
