IGBT characteristics. The IGBT or Insulated Gate Bipolar Transistor is indeed a hybrid MOSFET/BJT device. MOSFET's traditionally have low transconductance (gain). The old name for an IGBT is a GEMFET or Gain Enhanced MOSFET. As its name implies they have higher gain, but are a voltage controlled device (BJT are current controlled).

Structure used is build around TL494 working for PWM generation and high current opto drivers (TLP358) driving high speed IGBTs (GW30NC60) At this step, with 110Vdc supply, it reach 550W (29Veff) into 1.5ohms load. Will try to increase little more output power (to reach IGBT maximum rating). Sound is quite good, better than some chinese amplifiers

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. Therefore, the IGBT combines the advan- ... to MOSFETs in former audio amplifiers is highly undesirable. This mode of operation would lead to massively increased losses.
Insulated Gate Bipolar Transistor (IGBT) Basics
https://www.ixys.com/Documents/AppNotes/IXYS_IGBT_Basic_I.pdf
The Insulated Gate Bipolar Transistor (IGBT) is a minority-carrier device with high input impedance and large bipolar current-carrying capability. Many designers view IGBT as a device with MOS input characteristics and bipolar output characteristic that is a voltage-controlled bipolar device. To make use of the advantages of both Power
