Abstract

Chained inverters in high frequency, a.c. converter in high frequency and AC / DC converter in high frequency are adopted in the invention. When power network turns-off power, solar energy stored in accumulator is converted to AC electrical energy to supply to power network or load for keeping continuity of supplying power. When supplying power, power network supplies power for loads, and power energy is stored into accumulator. When voltage in power work is on the high side or in low side, the system supplies stable AC voltage for load. The system transfers energy in two directions providing continuous and stable electrical energy and high efficiency of converting power.

Description

Technical field [0001] The invention relates to a power supply system, in particular to a multifunctional solar power supply system. Background technique [0002] Such as figure 1 As shown, it is a traditional solar power supply system. The solar cell converts solar energy into DC power and stores it in the battery. The high-frequency inverter converts the DC power into a high-frequency AC voltage. The high-frequency transformer realizes electrical isolation and power transmission. The high-frequency rectifier converts the isolated high The high-frequency AC voltage is rectified into DC voltage, and then supplied to the grid or load through the grid converter inverter. [0003] The traditional solar power supply system has the following disadvantages: [0004] 1) The power needs to go through two-stage power conversion, the on-state loss of the system is large, and the efficiency is low; [0005] 2) The system can only transmit energy in one direction, that is, energy ca...
