Push-Pull Converter
Push-pull converters are used for very high performance ranges beginning at 1000 W.
Basically, a push-pull converter consists of two forward converters and therefore always
has two power switches. Using push-pull converters, every clock is used for power
transmission. As a result, the output power is much higher compared to forward
converters.
As with flyback and forward converters, the rectified line voltage U in is used as the input
voltage. The power switches S1 and S2 in the primary circuit are switched alternately by
means of the control voltage U ctrl . Both switches are never closed at the same time.
Otherwise, there would be no input short circuit. Each switching process of S1 and S2
causes the polarity of the primary winding N1 to change. The transformer is thus operated
with an AC voltage.
In every switching phase of S1 ad S2 the transformer Tr transmits power into the output
circuit. This power is then rectified by the alternately conductive and reversing diodes D1
to D4.
