APTGF300SK120G

APTGF300SK120G are IGBT modules, which are power transistors utilized to control voltage (VCE) and they have very high blocking voltage capability. IGBTs (Insulated Gate Bipolar Transistors) combine isolated metal-oxide-semiconductor (MOS) transistors and bipolar junction transistors (BJT) to offer superior characteristics over each respective individual component. IGBT modules provide efficient and cost effective solutions for higher power applications.

Application Field:

APTGF300SK120G are mainly used for higher power applications such as motor drives, industrial inverters, and power supplies. Additionally, IGBTs are widely used in DC drives, light dimming and power factor correction. APTGF300SK120G are rated at 1200V blocking voltage, which make it suitable for these applications.

Working Principle:

An IGBT module uses a gate-controllable switch that can be triggered on to turn the current on and off. The gate current through an IGBT is usually very small and can be controlled with an external voltage source. When a voltage is applied to the gate of the IGBT, a channel of carriers forms between the gate and emitter, allowing current to pass from the emitter to the collector. If a current is passed through the gate of the IGBT, the current flowing from the emitter to the collector will also increase. The IGBT switches current off when the gate voltage is removed. The IGBTs offer superior performance compared to regular BJT and MOS transistors due to their greater switching speed and higher efficiency.

Unlike a BJT, IGBTs can be switched on with an input voltage of a few volts. This means that low-voltage control circuits can be used to control high-power switching systems. This also results in improved efficiency in the system as less power is wasted due to lower control voltage.

When the device is operating, a voltage drop appears across the device which produces a low output voltage. This voltage drop is due to the nature of the IGBTs and it is called the "on-state" or "conduction" loss. This can make IGBTs less efficient than other switching devices, such as MOSFETs, in certain applications.

APTGF300SK120G IGBT modules are robust and reliable and provide optimal performance for higher power applications. These modules have various features and offer various benefits, such as high voltage and current ratings and robust design.
