ABSTRACT:
A tracking circuit for a power supply comprises an inverter (68), a summing network (70), and a driver circuit (72). The inverter inverts a feedback voltage, which is a variable load voltage level, about an inverter reference voltage level to provide an inverter output voltage level. The inverter output voltage level is summed or averaged with the output voltage of the power supply with respect to the voltage of the return line (54) to provide a summing voltage. The driver circuit signals the primary control circuit (35) to adjust the power supply output voltage level so that the summing voltage is held constant and equal with a driver reference voltage level.
