I'm watching from Russia. Everything is simple and accessible! Respect to the author! I have two questions for the author. 1. Why do I need a 10-mOhm resistor in this circuit? What does it give? 2. What is a 470 ohm resistor for? Is it possible to do without them and what happens if they are not installed? Can someone else, besides the author, explain in clear language and in detail?! With respect from Russia. \\ Смотрю из России. Всё просто и доступно! Респект автору! У меня два вопроса к автору. 1. Для чего в этой схеме, нужен резистор на 10 мОм? Что это даёт? 2. Для чего нужен резистор на 470 Ом? Можно ли обойтись без них и что будет если их не ставить? Может ещё кто-то, кроме автора, объяснить понятным языком и подробно?! С уважением из России.
Why are you using such a powerful reverse diode as a snubber? Use a resistor in series so that the current drops faster and does not heat the diode. P.S. the hall driver chip already has protection against EMF current.
Da kam man ja nichts sehen von welche Teile und so weiter , oder Gibst du nur an ? Wen schon was zeigen wollen dan sollte man auch was verstehen, so was ist null
Its good to test an IGBT, but you cant transfer 5A or 10A! or the IGBT will burn after Overheating, specialy if you have 60V input and 12V output!!! 60-12=48V , 48V*10A= 480Watt that means you produce 480Watt Heat in a 290Watt IGBT, and the Consumer get just 12V*10A = 120Watt :D Use a PWM circuit as a driver for IGBT, Mosfet, SCR ...
the linear voltage regulator has a low efficiency and generates a lot of heat on MOSFET. It is better to use pwm for this, or a dc dc converter. Also, you can assemble a PID controller for more speed control.
jsyk: I am a new fish. Mosfets don't like to be driven below gate threshold? Therefor the heating you mention? Using pwm means full gate threshold voltage every time the mosfet is switched? Did I get that right? But if the Mosfet is way over spec this circuit would probably work fine for a long time? These are things that I am trying to get straight in my head as I consider building my own.
