6 FAQs about [IGBT high frequency rectifier and inverter]

What is an IGBT rectifier?

A rectifier is an electronic device that converts alternating current (AC) to direct current (DC), and is commonly used in power electronics for various applications such as motor drives, power supplies, and industrial equipment. Traditional rectifiers use diodes as switching elements.

What is an IGBT transistor?

The most basic function of an IGBT is the fastest possible switching of electric currents, thus achieving the lowest possible switching losses. As the name “Insulated Gate Bipolar Transistor” reveals, an IGBT is a bipolar transistor with an isolated gate structure; the gate itself is basically a MOSFET.

What is IGBT & why is it important?

The IGBT, or Insulated Gate Bipolar Transistor, became the most used power electronic component in industrial applications. In the meantime it has become a central component in inverters for all types of electric drives, bat-tery chargers, and solar and wind power plants. But why? What is so special about this component?

What is the difference between IGBT and half-bridge converter?

The IGBT maintains near-ZVS operation but the diode is conducting a higher current. Low-resistive pans can cause the same effect for the diode. The half-bridge converter (HB) is one of the most popular topologies in power electronics especially in uninterruptible (UPS), solar inverters and motor drive applications.

Why is IGBT a good power electronic device?

As a power electronic device, the IGBT is optimized for high switching speeds. Operating it in linear mode similar to MOSFETs in former audio amplifiers is highly undesirable. This mode of operation would lead to massively increased losses. With the output characteristics of the bipolar transistor, further features of the device result.

How is filtered DC voltage applied to an IGBT inverter?

The filtered DC voltage is applied to an IGBT two-level inverter generating 50 Hz. The IGBT inverter uses PWM at a 2 kHz carrier frequency. The circuit is discretized at a sample time of 2 us The load voltage is regulated at 1 pu (380 V rms) by a PI voltage regulator using abc_to_dq and dq_to_abc transfomations.
