Modified sine wave is relative to the sine wave, and now the main output waveform of the inverter is the modified sinewave. The waveform of inverter is mainly divided into two categories, one is the (pure) sine wave inverter, the other is square wave inverter. Sine wave inverter output is the same as our daily use of the power grid, even better sine wave alternating current, because it does not exist electromagnetic pollution of the power grid.

Square inverter output is a poor quality square wave alternating current, it swift from the maximum positive value to the maximum negative value almost at the same time, so that caused severe instability to the load and the inverter itself. At the same time, the load capacity is poor, only 40-60% of rated load, with no inductive load. If the load is too large, the three harmonic components contained in the square wave current will increase the capacitive current flowing into the load, serious damage to the load when the power filter capacitor.

In view of the above shortcomings, in recent years, modified sine wave inverter is widely used, there is a time interval while the output waveform swift from the maximum positive value to maximum negative value, the effect improved, but modified sine wave is still composed of line, still belongs to the category of square wave, the continuity is bad and dead zone exists.

The modified sine wave inverter is generally used for the non isolated coupling circuit, while the pure sine wave inverter is designed by isolation and coupling circuit. Its price is also a lot of difference. Modified sine wave switching inverter power supply, not only eliminates the cumbersome power frequency transformer, but also greatly improve the efficiency of the inverter.

Modified sine wave switch mode inverter power supply with PWM mode generates a modified wave output, in the inversion process, due to the use of a specialized intelligent circuit and high power field effect tube, greatly reducing the power loss of the system. And the soft start function is added to ensure the reliability of the inverter. If the power quality requirements are not very high, it can meet the most demand for electrical equipment, but it still exists 20% of the harmonic distortion, the problems in the operation of precision equipment, also can cause high frequency interference to the communication equipment.

Frame type modular UPS, compared with traditional vertical (tower type) structure UPS, can be installed in the standard cabinet, save space, is convenient for installation and use and maintenance, is able to use a short power cable connection. By reducing the fault point between the key equipment and the load, the modular type UPS can improve the availability of the whole system.

The modular UPS includes rectifier and inverter, some also include static bypass switch and auxiliary control circuit, CPU main control board, etc.. The biggest advantage of modular UPS is able to improve the system reliability and availability, each normal failure and will not affect other modules in a module, and through the hot swappable to shorten the system installation and repair time.

In addition, the modular UPS can give users a better scalability, which also has played a very good protective effect for the user’s investment.

The installation and commissioning of modular UPS begin in the factory. Based on standardized modules, can develop a unified standard in product design and production and manufacturing process, let all the components of the whole system can display the best performance, also can avoid system failures due to compatibility problems.

Rack type modular UPS can be configured according to the current business requirements, and can add more modules in the future. The optimization ability of the system significantly reduces the total cost.

Modular design provides great flexibility in reconfiguration of power to meet changing business requirements. When installing, upgrading, re configuring or moving the modular system, the independent component and the standard interface and the simple operation can save time and cost.

In recent years, the rapid development of home inverter system is due to its unique characteristics. Its advantages are mainly in the following aspects:
1.Mainly composed of electronic components, does not involve mechanical components, no rotating moving parts, running without noise.
2.There is no combustion process, the power generation process does not require fuel.
3.There is no waste gas pollution in the power generation process, no waste water and waste.
4.Equipment installation and maintenance are very simple, low maintenance cost, reliable and stable operation.
5.Strong adaptability to environmental conditions, can work in different environments.
6.Be able to work under the condition of long time no one on duty.
7.It is easy to carry out the capacity expansion, expanding the scale of power generation.

Although the solar power system has many advantages, so far, there are still many problems that have not been solved. These issues are mainly concentrated in the following aspects:
1.Photoelectric conversion efficiency is very low. Twenty-four percent of the conversion efficiency is the world’s highest and temporarily unable to go beyond.
2.Photovoltaic power generation requires a large area. Although the photovoltaic power generation with the advantages of low-cost raw materials and the production process is simple, but the efficiency of the battery decreased with the area enlarging, this conflict to that the home power inverter systems need plenty of light and wide area.
3.The required illumination is complex, and the selection of the solar radiation should be appropriate. If the sun is not enough or cloudy or rainy or high temperater, the efficiency of the solar photovoltaic effect will be greatly reduced.
4.Photovoltaic power generation cost is too high, can not meet the requirements of large-scale popularization and application.

Electric vehicle as a development prospect of the broad green transport, the future will be very rapid pace of popularization, the future of the market is also very huge market prospects. In the context of the global energy crisis and environmental crisis is serious, the Chinese government actively promote the application and development of new energy vehicles, charge for power plants as required for the development of electric vehicles an important supporting infrastructure, with a very important social and economic benefits. A campaign to build an 220v EV charger / replacement station is already in the country.

The whole system is composed of four parts: portable electric vehicle charger, concentrator, a battery management system (BMS), charging management service platform.

220v electric car charger, the control circuit is realized by the embedded ARM processor, the user can self card user authentication, balance inquiries, billing inquiries, can also provide voice output interface, the realization of interactive voice. The user can according to the liquid crystal display to choose 4 kinds of charging mode: including charging, charging according to charge, automatically charging, charging according to the mileage, etc..

Electric vehicle charger controller and concentrators using CAN bus for data exchange, concentrator and the server platform using wired internet or GPRS wireless network data exchange, for the sake of safety, electricity charges and the amount of data realized security encryption.

The main function of the battery management system (BMS) is monitoring the battery working state (battery voltage, current and temperature), prediction power battery battery capacity (SOC) and the corresponding residual driving mileage, battery management to avoid over discharge, over charge, overheating and monomer battery voltage is seriously unbalanced phenomenon, to maximize use battery storage capacity and cycle life.

Charging service management platform has three main functions: charging management, charging operation, integrated query. Charging management related to the system of basic data for centralized management, such as information of electric vehicles, battery information, user card information, electric vehicle charging units information; charging operations mainly to the user for charging management, integrated query to query on data management and operation of the comprehensive analysis.
