Designing and analyzing an fpga based three phase inverter control system with variable phase controller

---

Pulse Width Modulation (PWM) Voltage Source Inverter (VSI) is widely used in many applications ranging from static inverter to variable speed drives. One of the important features of the VSI is the capability to control the phase angle of the output voltage for transferring the power output. This thesis proposes Field Programmable Gate Array (FPGA) based three phase control system with the variable phase controller. In this three phase inverter, the output phase voltage can be controlled as well as the output voltage. The controller developed has the feature to adjust the phase angle of each phase of the three phase power and the phase angle will be controlled to be very small so it won?t disrupt the three phase power. The thesis uses Insulated Gate Bipolar Transistor (IGBT) driven by IGBT driver which signal for the Pulse Width Modulation (PWM) to drive the IGBTs controlled by FPGA. The use of FPGA as the controller for this task can be considered for its efficiency and flexibility. Since the FPGA board does not have ADC circuit, the author proposes methodology to read the ADC using FPGA. This phase control methodology or system introduced in FPGA can be developed further to control the reactive power compensation by STATCOM method or bidirectional of the inverter.
