3 Phase inverter explanation? Answered
I am trying to make sense of how to create a simple 3 phase inverter, but the design I have found requires the use of a PIC micro controller for pulsed width modulation to control the 3 half inverters in the image below. I do not have experience with this specific type of micro controller and am unable to find a simple explanation of how to set it up to do this, except how to connect it to the basic circuit at the transistor bases. Would anyone be able to explain to me how to wire/program/control frequency with the pic micro controller or an alternative method that would yield 3 phase power (0-120-240) because the manual and this page have be very very hard to understand to a beginner. I do not need any sort of feedback from the motor because the load will be constant and relatively small, and will most likely run it either at a constant or if easily doable linearly increasing frequency. Can someone PLEASE give me a good simple set of instructions on how to either replace this micro controller with something simpler or wire/program it to do this? Thanks!
