WIDE RANGE POWER COMBINER
A wide range power combiner (WRPC) includes an electronics system that combines power from a plurality of input sources, which can differ in level, to at least a single output. In certain embodiments, a circuit can be constructed as shown in the figures (FIG. 1 ); a controller is used to generate a control signal to the switches, and for monitoring the energy storage elements. A possible control signal to the switches is shown in the figures (FIG. 2 ). The control signal, or signals, can dynamically change the frequency and order of switching to cause the switches to change the electrical connections of the energy storage elements, between the input and the output or outputs. A possible dynamic control algorithm is shown in the figures (FIG. 4 ). Switches can be any electrical switch, including transistors and relays. Energy storage elements can be any energy storage element, including capacitors and inductors.
