Abstract
This work deals with the switching losses comparison in hard-switching converter and soft-switching series resonant converter controlled by two different PWM algorithms. The first algorithm uses basic pulse-width modulation and the second one uses modified PWM which is improved at the lower duty cycle regime as shown in the article. The proposed converter shows the ability to switch from resonant mode to hard switching to achieve the lowest switching losses in whole output voltage range.
