Abstract: This paper presents a simple mixed-signal controller using OTA (Operational Transconductance Amplifier) – based circuit for the adaptive control system of shunt active power filter (APF). The dc bus voltage detection method is proposed for the control scheme. The simple OTA multiplier circuit, OTA-C Canonical second-order filter circuit and OTA-C plus OTA summator circuit is designed for the reference-sine-wave signal generator including Low Pass Filter and PI controller. The LM13700 is represented for the OTA simulated model which is developed for using with the 50 Hz three-phase three-wire system utility. The advantage of using OTA-based circuits is its adaptive control and real-time processing which can work with the high frequency power switches of the active power filter without using A/D converter. The simulation results show that OTA-based circuit can be used as the adaptive controller of APF which is simpler design compared to DSP, moreover, it can be fabri!
cated in one single chip by using CMOS technology.
