highest voltage switcher (half or fullbridge)

Started by Jamie M February 22, 2012
Hi,

Just curious what the highest voltage switcher people here have built? :)

cheers,
Jamie

450V Full bridge, 800V Buck, 1500V flyback.... Cheers Klaus

Your topologies refer to topologies hanging on the 'input' voltage. Is input voltage what you're after? Output voltages will depend on downstream configuration of transformers and rectifiers, and is loosly independent. RL

I did a flyback that made 2KV pulses about 3 ns wide.

Most of us have done better with an ignition coil - 20kV pulses several microseconds wide. -- Bill Sloman, Nijmegen

5kV, to deliver defibrillator pulses. -- Regards, Joerg http://www.analogconsultants.com/

Hi, I was wondering about how high the voltage difference can be for the primary to secondary coil on a half or fullbridge switcher, before something fails or becomes impractical, ie coil to core insulation etc. Could a fullbridge topology go to higher voltages and power more efficiently than a flyback, ie. for the same core from an old TV flyback, but not gapped for the fullbridge. cheers, Jamie

HVDC power transmission is something 500kV, might not really count as a switcher but it is DC that's chopped up and will eventually go to a transformer -Lasse
