Questions & Answers
I want to make an inverter with a Irf640, with a low pas filter on the output, would you help me with a schematic. chansa from Zambia.
Please provide the battery, load and waveform specifications of the inverter, i will try to help!
Howsit man
I’m curious and eager to know if I can make a voltage regulator using mp1620 and a irf620n mosfet, can you please guide me through the steps if possible. Thanks
Hi Wiseman,
Sure, you can certainly make a voltage regulator using IRF620 MOSFET. You can try the following configuration, and replace the MOSFET accordingly.
Please remember the input voltage must not exceed 150V, and the entire circuit is not isolated from the input high voltage, so be extremely careful…
Sir , specifications of how to design induction coil IC irs2453. .
Hello Shabbir, i do not have this circuit with me at the moment, so i am unable to provide you any help regarding this topic.
Dear Swagatham, is the current limited to the rating of zener diode or that of mosfet ?
Dear Suresh,
The maximum output current is determined by the MOSFET rating, the zener diode decides the maximum output voltage.
