| Summary: | 碩士 === 國立交通大學 === 電機學院電機與控制學程 === 106 === The current sensorless control for three phase half-bridge converter with power factor correction (PFC) function is presented in this thesis. Compared with conventional multiloop control methods, the proposed control strategy only requires two line voltages and two capacitor voltages to regulate the output voltage and achieve power factor correction. On the other hand, this control scheme can reduce the cost of circuits and simplify its complexity because there is no current sensor. Eventually, all the algorithms are implemented in a DSP chip TI TMS320F28335. The provided simulation and experimental results show the good performances of the proposed current sensorless control method.
