What is the recommended value of the reverse-bias voltage (-VGE) between gate and emitter?

A range between -5V and -15V is recommended. With lower –VGE, the turn-off time toff becomes large and the turn-off loss Eoff increases. Additionally, the IGBT may misfire and cause a short-circuit current flow.

What is the power cycle capability ΔTc?

Power cycle capability is the capability of the module to withstand repeated heating and cooling. The case temperature Tc will goes up and down until the modules fails: Stress strain is generated between the metal base plate and the insulating substrate causing fatigue in the solder under the insulating substrate. Refer to technical documents describing […]

What is the insertion load of the press-fit module?

Please refer to the Mounting Instruction.

Is an evaluation board for the IGBT module available?

A board for characteristic evaluation of the module is available. Please contact Fuji Electric Corp. of America or your local sales representative or distributor to answer your question.

What is the function of the brake IGBT, which is part of PIM and IPM?

When a motor stops, the brake IGBT is used to convert kinetic energy of the motor into electric energy and to consume the energy as heat of a resistor (damping resistor). Deceleration time of the motor can be reduced when using a damping resistor. Make sure that the DC voltage does not increase too much […]

What is the dead time?

“To prevent a short-circuit in the upper and lower arms, it is necessary to set an on-off timing delay between the different arms. During the so called ‘dead time’ period both devices are switched off. For details, refer to Chapter 7.3 of IGBT Module Application Manual.”

What is a RC-IGBT?

RC-IGBT is an acronym of "Reverse Conducting Insulated Gate Bipolar Transistor". The RC chip combines both, IGBT and FWD, in one single chip. It has excellent heat dissipation due to alternating operation of IGBT and FWD as well as reduced number of chips promise miniaturization and high reliability of the IGBT module.

How do I set up the shunt resistance for excess current detection of a small IPM?

Please refer to Chapter 4.2 of Application Manual.

Do you have small IPMs with formed terminals?

Please contact Fuji Electric Corp. of America or your local sales representative or distributor to answer your question.

Please let me know the carrier frequency characteristic of the control power supply consumption current of small PIM.

Please refer to the Technical Document of "Carrier frequency dependency of control power supply consumption current".
