Abstract

Most of the active filters used in power systems measure the load harmonics and compensate them to keep the supply current sinusoidal. Therefore, the accuracy of measurement is very important. Nowadays, active filters are usually controlled by microprocessors in the discrete time domain, where the sampling of the current signal is often coordinated with the PWM generation at the power electronics stage. This paper analyses the risk of aliasing, which introduces error in the measurement. Two popular PWM schemes are compared and it is shown that the aliasing effect will exist in both cases.
