The versatile bidirectional power supply is an integration of two systems: a DC-DC synchronous buck converter for charging a lead acid battery and a DC-DC synchronous boost converter for driving a CC-CV DC load from the lead acid battery. Control of the system is managed through an onboard MSP430F5132 microcontroller.
Bidirectional Power Directing Switches The purpose of the two switches is to channel the flow of power from the panel or to the load depending on the state of the system. When the system is in the battery charging state, MOSFET Q3A is turned on and MOSFET Q3B is turned off. Power flow occurs from the panel to the battery.
The bidirectional power stage operates at a 100-kHz switching frequency when working as a synchronous buck and operates at a 350-kHz switching frequency when working as a synchronous boost.
As a synchronous boost converter, the system can drive a DC load up to 45 V and 1-A current with close to a 92% efficiency level. This system works as a CC-CV limited power supply with configurable CC and CV limits. The system is especially suitable for DC loads that must be driven in CC mode, such as LED string and so forth.
