Transformer for RF
They can be used for interstage coupling(to match impedances for max power tranfer) in RF amps and also pass DC to bias devices when necessary. Lots of examples on the net.
TD Relay
For high power applications I've used a time delay relay switching in some power resistors in series with each side of the line. Say 10 Ohm 50Watt resistors in each leg. This will limit line current draw making it easier on the bridge rectifier also. The time delay should be greater...
High Voltage AC Supply
I've been wanting to make an adjustable 700-1000VAC (1-2amp adjustable current limit) regulated power supply. Variable 50Hz~1Khz frequency would be nice, but I would entertain single frequency. Would like to run it off 120VAC, and have output isolation transformer...
CREE SiC Rectifiers
Just to let some of you power electronics guys know. We were having some problems with major spiking goin on in one of our 1kw ZVS choke input switching power supplies.
Of course it was the rectifiers! We had soo much dissipation in our snubbers it was killing our...
Use current boost configuration

Just wrap a pnp around the regulator it increases current .You can implement current limit if you wish. It's up to you. Good LucK
how to make 1mh inductor coil
Make sure you observe the DC current rating of the inductor. Alot of these small surface mount inductors and others have hardly any inductace when large DC currents are being passed through them. Decoupling inductor or tuning inductor.
Q may be of importance, just...
