Hi, I want to build a motor drive circuit for a 170V 30A motor to control its speed by a PWM signal from a microcontroller , I'm a student and I'm new to this , I was advised to use IR2110 with two n channel mosfets , this is the circuit available in the IR2110 application notes ImageShack® - Online Photo and Video Hosting <img src="http://imageshack.us/photo/my-images/585/unled2is.jpg/"> I'm actually a computer and systems student , Electronics isn't really my strength point . However , I understand the overall circuit idea. 1st Question , Is this circuit the one I need? 2nd Question , it is mentioned that this schematic is for a 100mH motor , I don't know if this is would work with my motor or will I have to change something. thanks in advance.  |
