Power Supply Assembly

A charger is a common charging device that converts electrical energy into DC energy and outputs the electrical energy to electronic devices such as cell phones, tablets, digital cameras, etc. through a USB cable that connects the charger to the electronic device, thus enabling the charging process. The charger does not require the use of a computer or other device to charge, it simply needs to be plugged into a wall outlet.

Difference between square wave inverter and sine wave inverter

The square wave inverter outputs square wave AC with poor quality, and its positive maximum value to negative maximum value are generated almost at the same time. This has a severe unstable impact on the load and the inverter itself. At the same time, its load capacity is poor, only 40% - 60% of the rated load, and can not carry inductive loads such as motor, washing machine, refrigerator, relay, fluorescent lamp and so on. If the load is too large, the third harmonic component contained in the square wave current will increase the capacitive current flowing into the load, which will damage the power filter capacitor of the load in serious cases. In view of the improvement of the above shortcomings, the inverter has become a bright star in the photovoltaic new energy industry. In recent years, quasi sine wave inverter, also known as modified sine wave inverter, has emerged. Although its application effect has been improved, the waveform of the modified chord wave is still composed of broken lines, which belongs to the category of square wave and has poor continuity.

Sine wave inverter does not have the problem of electromagnetic pollution in the power grid. It outputs the same or better sine wave AC as the power grid we use every day. In summary, the pure sine wave inverter provides high-quality AC, high efficiency, stable sine wave output, high-frequency technology, small volume and light weight, and can drive any kind of load (including inductive loads such as TV, washing machine, air conditioner, water heater, LCD, electric ice box) without interference (such as Weng Weng sound and TV noise). However, the technical requirements and costs are relatively high.

The above is the difference between square wave inverter and sine wave inverter
