Abstract
This thesis presents the design and implementation of single phase inverter which produces an output voltage with a nearly pure sine wave. Cost-effective series resonant inverter is employed in several applications such as induction heating, sonar transmitters, fluorescent lighting, ultrasonic generators, standby power supplies and uninterruptible power supplies (UPS). The proposed inverter operates with high-frequency pulse-density modulation strategy for soft-switching. The high-frequency operation (20 kHz–100 kHz) of this inverter results in a nearly sinusoidal output fixed output applications. The series resonance circuit composed of an inductor and a capacitor connected in series with the load.
The small size of resonating components is due to the high- frequency switching operation. To analyze the performance, comparison between the simulation and experimental results is done by using PSIM program. The used sinusoidal pulse width modulation (SPWM) technique is generated by SG(IC). The designed inverter is tested on several AC loads. The proposed model of the inverter can improve the output waveforms of the inverter. The finished design is simulated in by using PSIM program to ensure the output results which are verified in the laboratory. The practical effectiveness of induction heating power supply is substantially proved by implementing a prototype series resonant inverter.
