Today we come to see the idea of High voltage spill equal. That can modify from AC 110V to DC 900V. When see the circuit also the technique Diode and Capacitors. Each other model conventional. Make voltage tall can go up , for this my circuit thinks. May give current get not tall , about 50mA. But usability should be careful specially. Because of it is high voltage. The detail adds friends , please read in the circuit. Request have the amusement with High voltage spill equal DC 900V , this please sir.
