Description
- TIDA-00476.2, Highly Efficient, Versatile Bi-Directional Power Converter for Energy Storage and DC Home Solutions. TIDA-00476 is comprised of a single DC-DC power stage, which can work as a synchronous buck converter or a synchronous boost converter, enabling bidirectional power flow between DC power source and energy storage system. Operating in synchronous buck mode, the system works as a MPPT controlled DC-DC converter which can charge a battery from a solar panel or DC Source. The same power stage can be operated as a synchronous boost to drive a DC load with configurable constant current and constant voltage limits (CC/CV), from an energy storage system such as lead acid battery. The power stage is digitally controlled by a MSP430 microcontroller, which implements the closed loop for controlling the power stage with required algorithms for MPPT, battery charge profiling and DC-Power conversion for load
