  • METHOD AND SYSTEM FOR RMS COMPUTATION ON DIGITIZED SAMPLES
    Publication number: 20090184695
    Abstract: A system and method for computing a Root Mean Square (RMS) value of digitized samples is disclosed. Discrete digital representations of a continuous analog electrical signal are produced. The discrete digital representations are received by a digital computation module, wherein the digital computation module is configured to perform a division operation and a square root operation for the RMS computation in one combined algorithm.

  • AC output power supply with digital feedback loop
    Patent number: 7502697
    Abstract: An AC power supply includes a digital feedback loop for output regulation. The feedback loop generates an RMS control signal that is mixed with a desired waveform to produce an input for a feedback loop that generates an instantaneous control signal. The instantaneous control signal is used to regulate power supply output.
