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.

The chapter presents the results of the development of two systems. The first is a photovoltaic system parallel to the power supply network of LED lamps. The algorithms of the system operation for both working and emergency lighting are shown. The basic operating modes of the system are considered taking into account the criterion of the minimum cost of electricity generated. These modes provide the most complete use of solar energy in the working day with minimal additional costs, allowing the consumer to save on electricity and increase the reliability of the emergency lighting system. The second system is a solar photovoltaic module built into a standard double-glazed window sash size 730x700 (mm), which is designed to charge a block of lithium-ion batteries with a capacity of 6.8 Ah with an output voltage of 5.25 V, the energy of which can be used to power any device having a USB 2.0 connector. The results of calculation of the required peak photovoltaic power of the module are presented; the technology of its sealing is described.

Voltage Jump

To realize the electric vehicle braking energy recycling and driving smooth, bipolar PWM modulation mode is often adopted. To avoid the bridge arm shoot-through, a dead zone needs to be set in the complementary upper and lower bridge arm driving signal. Using hardware circuit dead zone setting has the advantages of simple setting and high reliability, is often used in the integrated driving module, however different dead zone mode has different influence on the inverter output voltage. This paper carried analysis on motor speed nonlinear problems caused by output voltage jump around a specific duty ratio in hardware dead zone setting mode, and gives the improvement of hardware circuit. Simulation and experimental results indicate that the method can well solve the output voltage jump in the vicinity of a specific duty ratio problem.
