This design of the array of photovoltaic cells based on half-bridge circuit simulator, based on the DSP control, PI control and the addition of steady dynamic performance and improved accuracy system. 2 Solar cell operating characteristics When the solar cell is exposed to light, the photo-generated current flows through the load, thereby generating a load voltage. At this time, the equivalent circuit of the solar cell is shown in Figure 1. Among them, RS is a series resistor, Rsh is a side leakage resistor, also called a jumper resistor, which is caused by defects in the body or the edge of the wafer is not clean. Obviously, the bypass current Ish and the forward current ID of the diode (the total diffusion current through the PN junction) are supplied by IL, and the remaining photocurrent flows through the RS and flows out of the solar cell into the load. Thus, put the IV characteristics of the solar cell panel into a simple, convenient form of engineering calculations. 3 photovoltaic cell array simulator design Object simulator is to simulate a certain light, the electrical characteristics of the load varying with solar panel, including the maximum output power, the output characteristic IV, and the change under different sunshine. It should fulfill the following three requirements: (1) The system can complete the output according to the output characteristics of the PV array. When the external circuit load is constant, the system can maintain a stable output at the working point; (2) When the external load changes, the simulator can change to the new working point at a desired speed and can stabilize at that point; (3) Ability to output the required power; As a new type solar renewable resources are more and more attention, but during the development of the photovoltaic system, solar array by experiment since sunlight intensity, the influence of the ambient temperature, the experimental results in high cost, development cycle becomes long . Simulator array of photovoltaic cells can greatly shorten the study period the photovoltaic system, to improve the validity and efficiency of research findings.

Motor Aluminum Die Casting Housing FEATURES:
There are many factors affecting the quality of castings. The first is the design of the casting component. During design, in addition to the working condition and the metal material performance, designer should also consider the design from the characteristic of casting process and casting alloys, in order to avoid or reduce the casting composition segregation, deformation, cracking and other defects. The second is reasonable casting process. Namely select a casting type according to the structure, weight and dimensions. The third is the quality of materials used in casting process. Refractory materials, sand binder, and the quality of coating materials will also have an effect on the casting quality. Fourth is process operations, foundries need to control casting quality by making reasonable operation procedures and improving the technical level of workers.
• Casting is the process that molten metal flows into mold to form desired shape. Hence any complex shape can be easily produced.

• Practically any material can be casted.
• Ideal method is by producing small quantities
• Due to small cooling rate from all directions, the properties of casting are same in all directions.
