ABSTRACT:
A power supply system comprises a low-speed power supply and a high-speed power supply configured to operate in first and second frequency ranges, respectively, and generate first and second outputs, respectively. The lower end of the second frequency range is at least higher than a lower end of the first frequency range. A frequency blocking power combiner circuit combines the power from the first output with the power from the second output to generate a combined, third output for driving a load, while providing frequency-selective isolation between the first and second outputs. A feedback circuit is coupled to receive the combined, third output through a global feedback loop. The feedback circuit generates first and second power supply control signals for controlling the low-speed power supply and the high-speed power supply, respectively, based on a difference between the third output and the predetermined control signal.
