Solar energy is the source of all the energy on the earth, and the sun shines on every part of the earth. Wind energy is another form of solar energy on the surface of the earth. Due to different forms of the earth’s surface (such as sand, ground, vegetation, ground and water), the absorption coefficient of solar radiation is different, resulting in the formation of temperature difference on the ground surface, and then the formation of air convection wind energy. Therefore, wind energy and solar energy have strong complementarities both in time and in seasons: During the day, the sun shines well, the wind is small, at night there is no light, the wind is stronger; In summer, the intensity of the sunlight is large and the wind is small, and the sunlight intensity is weak and windy in winter.

The wind energy and solar energy resources in Inner Mongolia also have such complementary characteristics. The wind energy and solar energy resources in a certain place in Inner Mongolia are used to illustrate the complementarity between the two. The site is located at 42 degrees north latitude and 111 degrees east longitude, where the solar radiation is stronger during most of the year, when the wind is weak, and when the wind is strong, the solar radiation is weaker. It can be seen that the wind and solar energy resources in this site have good complementarity.

The wind and solar complementary power supply system is widely used in the rural areas of Inner Mongolia without electricity, farmers and herdsmen scattered households and centralized households, border companies and posts, border police stations and communication base stations, such as electric field, to provide users with living power and telecom facilities and other electricity.

Solar inverter is one of the power supply, and its production process and the required components is quite same to UPS, communication power supply and so on, China solar inverter industry is still in the early stages of development, but the develop rapidly.

According to statistics, Chinese solar inverter shipments reached 22.8GW in 2016. In 2016, The market of distributed inverters has become hot, inverter oligarchs also began to enter the distributed inverter market, launched a lot of small inverters. In 2016, centralized inverter market accounted for 62%, string inverter market accounted for 32%, the next string inverter, the proportion will continue to increase, to 2020 string inverter market share or to 45%.

As the industry is in the early stage of development, its competition pattern is not stable, there are many domestic solar inverter manufacturers, but the scale is generally small. However, in the domestic solar inverter market, Chinese manufacturers occupy the dominant position of the solar inverter market, the market concentration is higher.

The economic mode of UPS has great advantages, but the latest development of silicon carbide technology could offset the economic advantages of the mode, the transistor is the traditional silicon controlled device for UPS, insulated gate bipolar transistor (IGBT) function more and more powerful and reliable.

The UPS with IGBT device has an obvious disadvantage, the faster the switching speed is (to obtain higher accuracy), the higher the power loss. This is mainly because the upper limit of the module efficiency is 96.8%, and the efficiency of the dual conversion UPS can be increased to 98%~99% theoretically by using SiC devices.

The synthesis of silicon carbide powder has been mass production since 1893, the initial cost of manufacturing IGBT by using silicon carbide is very high, but the energy-saving effect is very significant, and all these are not the key to the power grid load transfer, will not increase the risk of power conversion.

At the module level, silicon carbide has two advantages: Smaller chip size and lower dynamic loss. At the system level, these advantages can be exploited in many ways. Low dynamic losses lead to a significant increase in output power, providing an opportunity to reduce weight and volume. It is worth mentioning that power increase can be achieved without additional cooling capacity, because compared with SCR, reduce the loss brought silicon carbide practical, can get higher output power under the same cooling condition. Low power loss can improve energy efficiency, allowing the design of more efficient inverters, so the UPS will be more efficient energy saving.

Therefore, if silicon carbide is used, UPS can no longer be operated in an economy mode, you can even eliminate online interactive UPS, as the user is able to less than 1% of the energy loss, it can get the comprehensive protection of voltage and frequency protection, who will need UPS to run in the economic model?

There have been customers bought a low-cost medical grade UPS, the power supply is 5V 200mA, hundreds of batches of the unit price is $5.
The device sells tens of thousands of dollars. The surprisingly low price of power seems pretty good. After opening this power supply, it is found that it has only one single-sided printed circuit board. In order to save the cost, the circuit board has no metallized through-hole. The circuit board adopts the surface mounting structure, and the component density is very large. The component spacing does not meet the requirements and design criteria of creepage distance specified by medical power supply and related safety management institutions. Leakage current up to 900mA, far beyond the specification limit. The creepage distance and the gap voltage can not reach the voltage used in the general power supply. The spacing between the high pressure regions is only 0.5mm, and the flux resistance is used to improve the dielectric resistance. The pin spacing of the MOSFET should have increased to increase creepage distance, but this power supply does not deal with this, probably because of the cost of manufacturing and this will take up more space. The aluminum fin is inserted into the circuit board by some claws, and then welded and fixed. Once the treatment is not correct, the radiator is easy to loose. MOSFET in flyback circuit is fullpak package with unkown manufacturer, there is a silicone jacket, and with insulating tape on the heat sink, which hinders the contact between device and radiator, which will have thermal stability may produce serious problems, that is heat sink is still cold when MOSFET has been hot. This power supply meets the commercial EMI-RFI requirements, but does not meet the medical power requirements.

This power has some other problems, such as the rosin joint in power supply everywhere. When using, even if the assembly is correct, also cause failure at any time. Although this power supply is sold as a medical UPS, it is not designed in accordance with the medical requirements. In addition to the input voltage and output voltage and current, there is no relevant documents and technical indicators. In addition to the surprisingly low price of this power supply, other performance are far from the requirements of medical power supply.

In the selection and purchase of hospital UPS, we must consider the risks, must be purchased from reputable manufacturers that provide quality and reliability standards and requirements.
