Isolated 15V To 2500V Power Supply Wiring diagram Schematic
This is the simple Isolated 15V To 2500V Power Supply Circuit Diagram. A dc-dc converter using a 74HC04 drives Tl. Tl is a ferrite-core transformer using a Fair-Rite, Inc. P/N 5975000201 (uo + 5000) and has a 7-turn primary and a 25-turn secondary. Kynar, #30 wirewrap wire is used. With Tl, the schema isolation is good to 2500 V.

Isolated Feedback Power Suplly Circuit
This is a power supply circuit using isolated feedback capabilities of the TL3103 for both current voltage sensing. This supply is powered from the AC power line and has an output of 5 Volts at 1.5 A. Both output voltage and current are sensed and the error voltages are applied to the errer amplifiers of the TL594 PWM control IS. See circuit below :

The 24 Volts transformer produces about 35 V. The 20kHz switching frequency is set by the 6-k Ohms resistor and 0.01uF capacitor on pins 6 and 5 , respectively. The TL94 is set for push pull operation by tying pin 13 high. A pair of TIP31 npn transistors are used as switching transistors in a push-pull circuit.
