sine3-v2 Three phase sinewave generation

Description

Uses trigonometry to produce high quality 3 phase output waveworms on the PWM. Tested from 30 to 100Hz at 10kHz modulation. Changes frequency glitch free. Amplitude is scalable. Could be used as a basic invertor back-end. Not optimised for processor overhead, could be modified to use lookup tables if less accuracy required.

Here is is changing between 1Hz and 2Hz (100% increment)
