The energy parameters of the photoelectric micro-power supply are analyzed based on the system structure characteristics and the power consumption of wireless sensor nodes. Meanwhile,the design theory model of the micropower supply is established by using the mechanism of the energy conversion,storage and transmission on the micropower supply. In addition,the infection of the energy storage mode,distribute mode and the sensor node working mode on the system characteristics and the design parameters is analyzed by using the design theory model. Meanwhile,the influence of both the energy management mode of the energy storage and energy buffer on the design model of system is analyzed. The results show that the system working and energy management mode are the main factors to affect the design parameters and working characteristics of the micro-power supply. The design theory model and analysis results lay a theoretical foundation for optimization design of the micro-power supply on chip.
