Highly Efficient: Versatile Bi-Directional Power Converter for Energy Storage and DC Home Solutions
Description
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.
Features
- Single bidirectional power stage working as both synchronous buck battery charger and synchronous boost CC/CV converter.High efficiency of 95% as charger to store energy and 90% as CC/CV converter to power loads.Perturb & Observe (P&O) based MPPT tracking algorithm.Robust Power stage with built in protection for Overcurrent: Overvoltage and Reverse Polarity Connection.Fully tested and validated as a MPPT based lead acid battery charger and CC/CV converter with LED & resistive loads.Simple use PCB form factor of 85 x 50 mm. provides a ready platform for single stage bidirectional power conversion needs of energy storage: DC Home and low power UPS systems.
