Technology Outline (Process Description)

The Multi-Port converter enables the integration and efficient management of multiple energy sources, storage systems, and loads within a single power system for rural applications.

Designed Multi-Port converter allows bidirectional power flow between two voltage levels while providing isolation between them. It consists of mult i active bridges, each comprising of power semiconductor devices i.e., MOSFET. The primary and secondary bridges are connected by a high-frequency transformer, which provides galvanic isolation between the two sides. The transformer also enables voltage step-up or step-down depending on the turn ratio. It requires that the full bridges generate two-level bipolar square-wave voltages with 50% duty-cycle and power transfer is achieved by techniques such as phase- shifting, pulse width modulation (PWM) control, current control loops, voltage control loops, and maximum power point tracking (MPPT) algorithm. The power flow can be effectively controlled by adjusting that phase shift, giving a simple control method with only one degree of freedom.

Compact and Sturdy Design: MPCs integrate multiple converters into a single unit to reduce the converter count necessary in systems.

Application: To provide power supply for rural home appliances through Multi-Port converter by integrating Renewable energy resources like Photo Voltaic and Wind Energy.
