LCC resonant circuit microcontroller microcontroller full-bridge inverter. LCC resonant circuit plasma load Abstract A full-bridge resonant inverter with digital controller for driving plasma load is proposed in this thesis. First, the proposed digital controller, including human-machine interface control, frequency controller, and phase-shift controller. According to the human-machine interface, the proposed system can compare the selected voltage from human-machine interface with the feedback voltage to stabilize the output voltage amplitude. Moreover, the implemented frequency control and phase-shift control are used to compare the system performances. Next, all the mathematical models and resonant circuit in all operating are derived. Then, the design criteria of resonant circuit is conducted. In addition, the primary side regulation (PSR) technique is need to overcome the difficulity in capturing the high output voltage to conduct the voltage feedback. Futhermore, the over current protection function is also incorporated into this system.
Finally, the power factor corrector (PFC), auxiliary power circuit and full-bridge inverter circuit are integrated in the proposed system. Besides, the measured output voltage of full-bridge inverter is close to the selected voltage under various output voltage conditions, and can drive the atmospheric plasma load successfully.
