    Hey all,

    New member here I found the site very helpful and decided to post up my current project as I have a few questions.

    I am in the process of putting together a single to 3phase converter.. I am using a rectifier to convert 120Vac 1ph to a 200DC bus which will feed my IGBT hex bridge.
    My inverter circuitry will look as follows:

    I am currently trying to wrap my head around the control signal processing.. I need to input three sine PWM signals 120 degrees apart to control my gate drive IC.

    DSP or MCU coding seems to be the most popular way of generating 3phase SPWM, unfortunately I am not very familiar with dsp/mcu programming so I was hoping to get some input on what type of dsp or mcu would be best for this particular application and where I can find any open source code related to 3ph spwm.

    Any advice or feedback is much appreciated.
