This paper is aimed at improving the output voltage waveform of a single phase PWM inverter. Two approaches is proposed, the first approach is based on selected harmonic elimination (SHE) of order up to 7th harmonic, for minimising harmonic distortion and modulating amplitude of the fundamental component of the output voltage waveform. For the first time, the Levenberg–Marquardt algorithm (LMA) ... Read more

ABSTRACT: This paper presents a novel circuit topology of voltage source multi resonant ZCS interleaved boost DC-DC converter with auxiliary quasi-resonant lossless inductor snubbers and capacitor snubbers. It uses two feedback loops, similar to current mode control, one for slow outer loop and the other for faster inner PWM control loop. To improve the transient response of the 2-cell converter ...
