High Voltage, Low Noise DC/DC Converter Circuit Designs

Have you seen the Linear Technology application note on high voltage, low noise DC/DC converters? Ap notes don't get any better than this one. It includes circuits for high voltage power supplies rated from 200V to 1000V. It also addresses noise issues, and the effects of various voltage feedback techniques on transient response.

The ap note describes resonant Royer topologies (which produces power by utilizing sinusoidal waveforms instead of switched waveforms) and also flyback converters. It also describes methods of measuring output noise.

If you are planning to design a high voltage power supply for photomultipliers (PMT's) or other applications requiring low noise, low power in the range of hundreds of volts, you might want to peruse the ap note. It is Linear Technology Application Note 118.
