TMDSSOLARCEXPKIT: Running SEPIC with External PWM signal

Part Number: TMDSSOLARCEXPKIT

Hey,

I am building an off grid battery charging / inverter project using the TI C2000 Solar Explore Kit.

I was having problems configuring the ADC pins to implement control of the inverter and and SEPIC simultaneously

So I am trying to control the SEPIC externally with an Arduino DUE.

I was just wondering two things:

1) Will I be able to send a signal from the Arduino digital pin (3.3v) to the pad of the SEPIC. (The F28035 will only be sending signals to and from the inverter)

2) What is the formula for the Duty cycle (DUTY4A) for the SEPIC side? (PWM for the MOSFET)

Thank You very Much

I am not sure why you say you are unable to control using the control card on the kit itself,

we have a project for precisely this.

Im trying to run both the Inverter and SEPIC at the same time.

Looking to build a grid-tied inverter / battery charging system.

I can run the inverter project by itself, and the Batt charging project by itself, but couldn't find a way to integrate the two project together.

unfortunately we do not have a project that combines them in a storage application, good luck with your project.
