ap400b
Thanks for the reply, G4BCH. Unfortunately, the capacitance of this load is a lot higher than found in a CRT 'scope so I need to deliver "real" (er, apparent) power here. Right now they are using an ENI AP400B 400W power amplifier to drive the device* at 250kHz, 440Vpp and the amplifier...
1 mhz power amplifier
Hey all. A physics professor friend of mine asked me to build an amplifier that could deliver 300Vpp across a purely capacitive load (literally, alternately polarized plates in a vacuum) with a 100kHz to 1MHz sine wave. This didn't seem like a very challenging problem to...
buck current mode error amplifier
If you want to get serious about smps design you will definitely want to get both Abraham Pressman's and Keith Billings' books on such. In the meantime, Texas Instruments (which bought smps controller pioneer Unitrode some years back) has a lot of excellent app...
