A multi-mode renewable power converter system is disclosed. The system includes
a control unit, a boost converter, an inverter and optional bi-directional charger,
wherein the boost converter converts DC output of a solar cell or a renewable source
to high DC bus voltage, and the inverter converts this DC bus voltage to an AC
output. This power converter can be used to support standalone load or grid-connected
system with a dynamic maximum power point tracking (MPPT) circuit. The MPPT circuit
detects the current and voltage from the solar cell and indicates to the inverter
to provide power to the load connected. When the optional bi-directional charger
is installed, the MPPT signal is also fed to this charger to make the power efficiency
maximized for the system.
