Why can't most of the modified wave inverters load LED energy-saving lamps?

1.LED belongs to inductive load. The current LED string has a capacitor current limit. The capacitor is charged with about 300 volts DC during charging. This DC voltage and the 300 volts in the inverter are stacked in series to 600 volts. It is easy to put the withstand voltage at only 500-600 volts. Inverter output MOS tube breakdown.

2. Modified sine wave is also divided into two kinds, one is an ordinary, ordinary repair sine wave, just the square wave into a simple correction, one is a good, the other wave is a better correction. High quality repair sine wave with LED lights.

Ordinary modified sine wave has many restrictions on the load, such as with resistive load (incandescent lamp, electric furnace (except induction cooker) and other loads) is no problem, but capacitive load (such as rechargeable LED flashlight) will appear on the edge of the pulse Inrush current causes capacitive load to be easily damaged when the modified sine wave power is supplied, and the work of inductive load (electrical equipment using the motor) may also be abnormal

Solar PV inverter market to decline over next four years

The report  Solar PV inverters – Update 2018  says that Asia Pacific, currently the leading market for solar inverters, with a market valued at £3.75b in 2017, will suffer the most and see its market share fall from 59%  to 38% in 2022. The Americas market is expected to grow from 27% to 41% and EMEA (Europe, Middle East, and Africa) will increase from 14% to 21% in  the period 2017 to 2022. Subha Krishnan, Power Analyst at GlobalData, said: “In terms of market value, China, the US, and Japan together held over 65% and led the global solar PV inverter market in the year 2017. The market developments in the top countries are largely due to economies of scale, emerging inverter technologies, and policy-based government and institutional industry.” Between 2017 and 2022, the global solar PV inverters market is expected to witness a negative compound annual growth rate (CAGR) of 10.15%, in terms of market value. The estimated fall of an avera...

whats the trend and significance of Digital Control System Based on SCM? What is its advantage?

With more and more applications of inverter power supplies, the demand for the development of inverter power supply technology is also increasing. At present, the design of inverter power supply adopts a structure composed of discrete components designed by pure hardware. As the number and type of appliances used by people increase, the higher the waveform and capacity requirements of the inverter power supply, the higher the complexity of the inverter power supply design and the more components used. However, due to the excessive number of components and the poor stability of the power supply, the entire system is often damaged due to poor quality of a component. In addition, the traditional inverter power supply is based on the design of analog components and has no programmability, which makes the reversible power supply less scalable and has no display function. Therefore, the microcontroller is very important as the master chip of the inverter power supply. With the deve...
