Hi,
I'm in the design process of a speed control for 3 24 volt dc fans with sensors input to a microcontroler. I'm using the pwm output of the microcontroler to control the 3 fans speed. I'm using a 24volt power supply for the fan using about 150 watt. My question is : Is there any reason I...
Hi,
I building a 24vdc power supply at 7A ouput with four 2200uf capacitor for a total of 8800. I have some trouble selecting the right transformer for my application. Simulation give me a high peak current in the transformer but I'm not sure if this will make the transformer overheat and if...
Hi, I'm currently in a design phase of a variable speed 48vdc control for a fan. I want to connect the fan on the ac line so i need a ac to dc converter. I found out that the best solution is probably to use a switch mode power supply for the firts stage and a pwm buck converter to control the...
Hi, I'm in the design process of a non-isolated buck converter to get 70Vdc from the 115vac line and I have some trouble controlling my mosfet. I'm trying to control the mosfet from a microcontroller using a hcpl-3180 from avago technologie. The mosfet is on the high side, so I need a floating...
