Recientemente abrí la simulación en LTSpice. Aunque conozco el programa, no estoy completamente familiarizado con él. Modifiqué los valores de inductancia que había calculado previamente y obtuve las tensiones que se muestran en la imagen. No vi la necesidad de reemplazar los componentes por los...
Hello, thanks for your response. The truth is that I don't know much about cascade converters. I tried to make a boost converter, but the problem I encountered was with the Vpk and Ipk. Also, since I didn’t have MOSFETs, I had to use NPN transistors, which, due to their response time, overheated...
Hello, in that sense I agree with you, the 3842 has an advantage over the 34063, but I couldn't get it, at least at a reasonable price. Also to speed up the shutdown I was planning to use a 1K resistor with a 2N3906, as a diode will a 1N4148 do?

I am designing a flyback source using the MC34063 IC with the goal of raising the voltage from 12V to 500V and providing an output current of 10mA. My idea is that the output is adjustable by means of a potentiometer, modifying the feedback voltage. This power supply is intended to power small...
Hi
I was needing a variable power supply between about 50V and 400V, with a current of only a couple of milliamps, to reform electrolytic capacitors in valve equipment. To do this, I came up with the idea of designing a boost converter using a 555, with a small feedback towards pin 5. However...
