The comparison of the proposed constant power converter with the traditional power converter with inherent soft switching and power factor correction is presented. The constant power converter circuit is implemented and is used to charge a battery. The improvement of the power factor is achieved by the boost converter. The replacement of the single winding transformer by the center tapped transformer increases the output voltage and reduces the size of the circuit. Harmonics and ripples were observed in the circuit which is reduced using filter. The reduction in cost, compactness and power factor correction makes the constant power converter circuit utilization in high frequency applications. A 60% reduction in ripple is achieved by this constant power converter circuit. Hence it provides a better solution compared with the conventional circuit. The objective is to design a constant power converter circuit and also, to simulate the constant power converter circuit as well as the conventional circuit. AC input voltage and current, boost converter voltage, and DC output voltage time waveform of the above-mentioned circuits are observed and analyzed, further being implementing the converter circuit using constant power mode.
