Compiler: C200 or MSP430 for solar charge controller

Tool/software: TI C/C++ Compiler

Good day,

I am looking to purchase either the C200 or the MSP430 for my system and I want to know which one will best suit my system and why?? I need to control 2 converters independently. The first converter I will implement P&O MPPT and the second one I will do 3 stage battery charging control. My switching frequency is 100kHz. Are there any reference source codes for my application that I can look to? Your response will be appreciated.

    Hello,

    High performance C2000 MCUs have a history of being applied in solar projects and are purposely designed with accurate sensing and efficiency in mind, which is critical in a system like yours. The precise sensing capabilities provided along with C2000’s ability to perform high frequency control loops will best allow you to maintain the maximum power point while preventing battery overcharging, thus maximizing battery life. Furthermore, C2000’s accuracy is ideal for ensuring that your battery charge controller is able to effectively identify and regulate voltage and current throughout each power stage.

    In addition, C2000 is compatible with TI’s DigitalPower SDK and PowerSuite, which were designed to minimize power system development times. The software includes firmware that runs on C2000 digital power evaluation modules and TI designs which are targeted at solar and other power delivery applications.
