Abstract
An apparatus and method for delivering power from a D.C. voltage source to one or more D.C. loads rated at lower voltages. The invention provides for the repetitive application of the higher D.C. voltage to the loads for a predetermined time period sufficient for the load to operate yet not too long to ensure that the load will not be damaged. To implement the invention, a clock signal provides the time reference for separate slots allocated for the time periods associated with each of the loads. A user selectively enables or interrupts the repetitive connection to each of one of the loads. The rate of repetition of the connection of the high voltage source could vary from 60 to 200 Hertz, preferably without degrading the operation of typical loads.
