摘要：

Two real-time algorithms for active power measurements on Pulse Width Modulation (PWM) electric drives are proposed, The former is an off-line algorithm reducing truncation error through an accurate signal period estimation and a proper window, The second is an on-line algorithm based on a low-pass IIR digital filter with an optimized transient phase, Numerical results of the metrological characterization of such algorithms, aimed to suggest criteria for their use, are presented, The experimental results of tests carried out on an actual drive confirm numerical simulations and are in perfect agreement with those of a well-acclaimed algorithm.
