Good Book on Power Electronics?

 		I'm looking for a decent book to improve my rather patchy knowledge of power electronics. I'd like something reasonably general that covers motors, power distribution, switching, SMPS, etc. A lot of textbooks are sadly not very clearly written. I'd like to get something with the clarity or redability of The Art of Electronics or The American Radio Relay League Handbook.

All suggestions appreciated.

 		I use "Power Electronics - Converters, Applications, and Design", (Wiley 3rd ed.) by Mohan, Undeland, Robbins.

 		We're using that book too, unfortunately the author thinks that all 4 diodes in a bridge rectifier can be on at the same time.

Depending on the reverse recovery time... very briefly they can all be on.

 		Also if you're driving an inductive load (eg, a choke input filter rather than the usual capacitor input filter) they will all come on around the zero point of the line voltage. If the AC line has a lot of inductance too, the waveforms get really complex. These are the kind of questions that people setting power electronics exams love, and I hate. sad

You sometimes see a fifth flywheel diode across the DC output, so it only has to flywheel through one diode drop instead of two.

In a related topic, the two diode full-wave rectifier you find in an ATX PC power supply has both diodes on during the PWM deadtimes. Since they are effectively in parallel, there's no benefit to adding a third flywheel diode.

‘Power MOSFET Design’, Taylor, B.E., Wiley, 1993
‘Power Electronics’, Lander, C.W., McGraw-Hill, 1993,
‘Switched Mode Power Supplies in Practice’, Kilgenstein, O., Wiley, 1993.

There's another one that I saw in Alan Sharp's library, but can't remember.

 		Thanks everyone. I'll start with the Lander book.

Also, I noticed that National Semiconductor is holding FREE online lectures. I haven't attended one yet, but they've got a ton, especially related to SMPS. (and their chips!)
