Inverter sine wave igbt

It handles power conversion and energy transfer inside the inverter. JOEYOUNG uses high-quality IGBT modules in all their inverters, like the 3000W solar inverter and the 12V 2000W pure sine wave inverter. This article will explain the definition, working principle, advantages, and disadvantages of Inverter IGBT.

The inverter's IGBT is like its heart. It handles power conversion and energy transfer inside the inverter. JOEYOUNG uses high-quality IGBT modules in all their inverters, like the 3000W solar inverter and the 12V 2000W pure sine wave inverter.

The IGBT is a voltage-controlled device, which gives it the ability to turn on and off very quickly. Figure 1 shows atypical application of a three-phase inverter using six isolated gate drivers.

The efficiency of an inverter indicates how much DC input power is converted to AC power on the output. High quality sine wave inverters deliver 90-95% efficiency. Lower quality modified sine wave inverters are simpler, less expensive and less efficient, typically 75-85%.

As the name indicates, an IGBT is a bipolar transistor with an isolated gate structure; the gate itself is basically a MOSFET. Therefore, the IGBT combines the advantages of high current-carrying capabilities and high blocking voltages of a bipolar transistor with the capacitive, low power control of a MOSFET.

The Modified Square Wave also known as the Modified Sine Wave Inverter produces square waves with some dead spots between positive and negative half-cycles at the output. The cleanest utility supply like power source is provided by Pure Sine Wave inverters.
