Abstract

A fast peak detector for three-phase variable frequency sinusoidal signals is proposed. This new detector fully uses the three-phase characteristic to achieve instantaneous response, frequency and phase sequence independence characteristics. Also, the proposed detector possesses excellent linearity and low sensitivity to phase unbalance and harmonic distortion. Theoretical basis, hardware implementation, and experimental results are all detailed in this context
