Es. Da Silva et al., An improved boost PWM soft-single-switched converter with low voltage and current stresses, IEEE IND E, 48(6), 2001, pp. 1174-1179
This paper presents an improved regenerative soft turn-on and turn-off snub
ber applied to a boost pulsewidth-modulated (PWM) converter. The boost soft
-single-switched converter proposed, which has only a single active switch,
is able to operate with soft switching in a PWM way without high voltage a
nd current stresses. This is achieved by using an auxiliary inductor, which
is magnetically coupled with the main inductor of the converter. In order
to illustrate the operating principle of this new converter, a detailed stu
dy, including simulations as well as experimental results, is carried out.
The validity of this new converter is guaranteed by the obtained results.
