The article introduces the design of the half-bridge switching and regulated power supply system which is based on PWM. The design mainly consists of regulated power supply’s structure of basic hardware circuit, its working principles and the process of modeling simulation and software design. The control circuit controls SG3525 chip to output PWM wave through the Microprocessor Control Unit (MCU) of AT89C51 and drives IGBT through the chip of EXB841 as well. The MCU is also used to realize the keyboard process and controls of the pulse width and frequency. Taking advantage of Simulink (dynamic simulation Toolbox) and SimPowerSysterm (power simulation Toolbox) of MATLAB, it simulates the designed regulated power supply. According to the simulation result of this design, the system has high stability and good output waveform. The operation of the design is simple and clear with less software operation and higher speed.

Based on the preliminary study of the distribution of wind and light resources in the Zhongshan Station of Antarctica, and the conclusion that the scenery and resources of the station area are sufficient and complementary, this paper proposes to adapt to the power supply problem of the aeroponic, stereoscopic cultivation device in the Controlled Micro-environment applied to the polar regions. The overall architecture of the power supply system is designed. Based on the STC8A8K64S4A12 single-chip microcomputer, the hardware circuit and software program of the wind and solar hybrid power supply system controller are also designed. Finally, the debugging experiment is carried out.
