Triple PWM Testboard
PIC18F1330 and high power PWM
Just for fun I developed this neat, little PWM evaluation board. Containing a USB interface, a rotary encoder and three half bridges capable of providing 8A at 100V max, this board provides a very versatile small, yet powefull development platform.
Since this is work in progress, and since I started the project only two days ago, I can't provide much information yet. Drop me a line for the preliminary schematic, or code.
But I have a nice picture:
Currently I have wiritten a small programm, that generates three sine waves, each with its own phase. The incremental encoder sets the frequency, and current data is send out over the USB interface. All works nicely.
A further update including some code will follow soon.
