A power-meter includes a digital signal processor (DSP) configured to determine a respective consumed energy within each of a plurality of predetermined contiguous time intervals, a dequantizer, and a pulse generator. The dequantizer is configured to, for each time interval, determine a sum of a remainder and the consumed energy, calculate an integer pulse-count by dividing the sum of the remainder and the consumed energy by a predetermined pulse-quantum, calculate a new remainder by subtracting the product of the integer pulse-count and the pulse-quantum from the sum, and replace the remainder by the new remainder The pulse generator is configured to, for each time interval, generate the integer pulse-count number of pulses of an indicator signal.

A power detector is disclosed. The power detector includes a primary-side sense circuit configured to generate a sense signal representative of an output voltage of a flyback converter. The power detector also includes a primary-side reference generator configured to generate a reference signal representative of an average output current of the flyback converter. The power detector further includes a primary-side power calculation circuit configured to generate an output-power signal in response to the sense signal and the reference signal.
