A Pseudo Randomly Triggered Integer Cycle Control (PRT-ICC) for AC Loads to Reduce THD, EMI and RFI
Abstract: Several proportional voltage control techniques exist for AC loads. The most popular of these are phase control (PC), cycle control (CC) (including integral cycle control (ICC) and fractional cycle control (FCC)) and pulse-width modulation (PWM)). Phase control utilizes triggering for loads away from zero voltage or zero current and generates odd harmonics with amplitudes higher than ICC and PWM. Integral cycle control, causes more harmonics (both even and odd) overall …
