An inverter is an electronic device that converts low-voltage direct current into alternating current and it is composed of inverter bridge, control logic and filter circuits. Inverters can be divided into square wave inverters, modified wave inverters and sine wave inverters according to their output waveforms. Pure sine wave inverter is an inverter whose output waveform is a sine wave.

Advantages of Pure Sine Wave Inverter

The big difference between pure sine wave inverter and ordinary inverter lies in that the output waveform of pure sine wave inverter is a completely sine wave, featuring low harmonic distortion, and its output waveform is basically the same as the AC waveform of the mains power grid. In fact, pure sine wave provides higher quality AC power than the grid. Therefore, the sine wave inverter features little interference to radios, communication & precision equipment, low noise, full protection functions as well as high overall efficiency, and can meet all AC load applications with strong load adaptability.

How does a pure sine wave inverter work?

The pure sine wave inverter works into three stages, the oscillation, the amplify and the output transform.

  • Oscillation: The inverter generates oscillating pulses through the IC circuit. These oscillations generate alternating positive and negative voltage peaks at a specific frequency.
  • Boost or amplification: The AC voltage generated by the pure sine wave inverter oscillator is amplified to a high current level in this stage. The amplified electricity is in the form of AC, but the voltage is very low, and it is still at the battery-powered level.
  • Output transform: In an AC-to-DC transformer, through the magnetic induction of the two windings of the transformer, the power supply will reduce or step down to reduce the specified AC level. The transformer in a pure sine wave inverter works in the similar way. The low-level alternating current from the inverter amplifier stage is applied to the secondary winding of the transformer in the output transformer stage. This process results in a voltage boost, which is used by the inverter to power AC equipment.

Applications of Pure Sine Wave Inverter

Pure sine wave inverters adopt sophisticated technology to protect sensitive electronic devices, and are widely used in digital microwave ovens, TVs, refrigerators, laptop computers, laser printers and other electronic devices. Pure sine wave inverters can supply power for most AC equipments without the risk of damaging equipments. 

Nowadays, an increasing number of people use pure sine wave inverters. It is worth noting that we believe that pure sine wave inverters with a conversion efficiency of less than 80% have no purchase value. However, you can shop with confidence when you purchase pure sin wave inverter at Peaco Support store because our pure sine wave inverter has max. efficiency up to 90%.
