Abstract : High-frequency switching is used to minimize the size and to improve the system performance. Most of the power supplies derived from ac mains source. The rectifier based PWM inverter has front end bridge rectifier with smoothing capacitor. As a result, the input has distorted line current and poor factor. The square wave inverter has non-sinusoidal output current. It affects the system performance and increases the switching loss and reduces the efficiency. All these problems affect the Ozone production and system efficiency. These problems are solved through proposed method. This paper presents the Power Factor Corrected (PFC) converter with parallel resonant inverter based power supply for ozone generator system. The proposed system has active power factor correction converter and Parallel resonant inverter which are used to achieve sinusoidal current and improve the supply power factor and zero-voltage switching across all switches. The active PFC converter with parallel resonant inverter fed ozone generator generates more ozone output compared to the conventional inverter. Thus the proposed system has less switching loss, less current harmonics, and better input power factor compared to the conventional system. The performance of the both inverters are compared and analyzed with the help of simulation results presented in this paper. © Springer India 2016.
