Abstract
A floating output power supply includes circuitry for indirectly sensing an output current and output voltage of the floating output power supply. The circuitry includes a circuit ground referenced current sensing resistor placed in between diodes forming one leg of a full wave rectifier. The voltage of this current sensing resistor is circuit ground referenced and representative of an output current of the floating output power supply. A resistive network is coupled between a negative output and a positive output of the floating output power supply. The resistive network includes a circuit ground referenced resistor whose voltage is representative of the output voltage of the floating output power supply. A controller of the floating output power supply determines output voltage, current, and/or power from these sensed voltages and currents and adjusts an operating parameter of an input power supply as a function of the determined output voltage, current, and/or power.
