Constant output voltage in buck-boost converters
I'm a self-taught student. I'm trying to understand the working principle of buck-boost converters in continous conduction mode.
When the switch is turned on, the equation describing the inductor is ...

Forward biasing of diode bridge in a discontinuous mode operation of a three phase buck-boost derived power factor corrected converter
In this paper, they said that during mode 1 the diode bridge is forward biased because the output capacitor voltage is greater than peak line to line voltage but during mode 2 they are forward biased. ...

Reversible 4-switch buck-boost?
Can a 4-switch buck-boost be reversible?
The base scheme seems symmetrical but I did not find any reversible design.
Do you have an exemple of such a design?

How does a boost converter allow for a gain in output voltage by just switching the positions of the inductor and switch?
I get that in a buck converter, a low pass LC circuit was attached and this effectively filters out high frequencies. If the bandwidth is configured so that it is lower than the switching frequency, a ...
