A problem book, not a worked-answer list
Power electronics punishes the student who reasons only in averages. A converter is a circuit that changes its own topology several thousand times a second, and almost every quantity worth knowing — output voltage, ripple, device stress, harmonic content — comes from integrating over one switching period and then asking what the answer means for a real device with a real thermal limit. This companion to the Power Electronics textbook exists to give you that practice several hundred times over.
Every problem here is solved in full. Not a final answer with the middle omitted, but the actual sequence of decisions: which conduction interval is being analysed and which devices are on during it, whether the converter is in continuous or discontinuous conduction and how that was established rather than assumed, why volt-second balance was applied to that inductor and charge balance to that capacitor, and how the result was checked against the device ratings. Where a step commonly goes wrong — an RMS taken over the wrong interval, a firing angle measured from the wrong reference, a peak inverse voltage quoted as the supply peak when the source inductance says otherwise, an efficiency computed from a duty ratio that no longer holds in DCM — the solution says so.
The forty sets below cover all seven parts of the textbook, from the reverse-recovery charge of a single diode to the reactive-power set point of a STATCOM. The parts mirror the book exactly, so a set can always be read against the chapter that derives its method.

Most marks lost in power electronics are lost before any converter appears: an average taken over the on-time instead of the whole period, a volt-second balance written for an inductor that was never in steady state, a duty ratio confused with a conduction angle. The first set drills exactly those habits on waveforms simple enough that the arithmetic never hides the reasoning. Work it through even if it looks beneath you — the thirty-nine sets that follow assume every one of these reflexes. Open Set 1 →
