What is a Modified Sine Wave Inverter?Modified sine wave inverter definitionA modified sine wave inverter, also known as a modified sine wave inverter or quasi-sine wave inverter, is a device that converts direct current (DC) into a sine wave-like alternating current (AC). The waveform produced by this inverter is not a completely smooth sine wave, but a stepped waveform composed of multiple rectangular waves.Working principleThe modified sine wave inverter works similarly to a pure sine wave in

What is a Pure Sine Wave Inverter?Pure sine wave inverter definitionA pure sine wave inverter is a device capable of converting direct current (DC) into alternating current (AC) that is very close to the ideal sine wave form. The quality of the alternating current generated by this type of inverter is very high, almost equivalent to the quality of the power provided by the mains grid, so it is suitable for occasions where the quality of the power supply is high.Working principleThe core technolo

What is a Sine Wave Inverter?Sine wave inverter definitionA sine wave inverter is an electronic device capable of converting direct current into high quality sine wave alternating current. Compared to square wave inverters or modified sine wave inverters, sine wave inverters output AC waveform closer to the ideal sine wave, so they can provide a more stable and efficient power supply for various types of loadsThe operating principle of the chord wave inverter is based on complex power electronic

What is a Square Wave Inverter?Square wave inverter definitionSquare wave inverter is an electronic device that converts direct current into alternating current, and its output alternating current waveform is in the form of square wave.Working principleThe working principle of the square wave inverter is based on simple switching technology. It uses electronic switches (such as relays or transistors) to periodically turn on and off DC power, resulting in alternating currents. Since the waveform

What is AC Charging Pile?Ac charging pile definitionAc charging pile is a facility used to provide AC charging for electric vehicles.
