Portable multi-energy micro-energy power generation device and method

The invention provides a portable multi-energy micro-energy power generation device and method, and relates to the technical field of new energy power generation. The device comprises a power generation module, an MPPT module, a wind energy and water energy hand power generation control module, a pressure power generation control module, a pressure power generation energy storage module, an electric energy storage module, a battery charging module, an energy path control module, a battery protection module, a battery pack, a direct current bus, a USB output module and a central control module. Compared with a traditional fixed voltage method or perturbation and observation method, the MPPT algorithm based on the variable step size perturbation of the terminal voltage PD change rate improves the power generation efficiency of a photovoltaic module on a human body in a complex motion state, adjusts the voltage of a bus based on a micro-energy path management strategy triggered by an event, balances output energ
