Low-power switched-mode power supply converters are used in applications where size and efficiency are critical. The buck converter size can be reduced by elimination of the bulky filter capacitor. The filtering function of this capacitor can be replaced by an output current ripple compensation circuit. The compensating circuit is applied, based on inductor current measurement and linear amplif...

Many applications (electric vehicles, renewable energies, low-voltage DC grids) require simple, high-power density and low-current ripple-boost converters. Traditional step-up converters are limited when large transformation ratios involved. In this work is proposed a converter that brings together the characteristics of high gain, low ripple, density. From proposal, mathematical analysis its o...

A soft-switched inverter is derived from the passively clamped quasi-resonant link circuit with three different clamps: coupled inductor, diode clamp and coupled inductor and capacitor. The proposed soft-switching inverter is formed from the traditional pulse-width modulated (PWM) inverter by simply augmenting with auxiliary resonant circuits, and the soft switching is achieved through applying...
