[Data] Shirutoku Report No. 64 #Power Semiconductor (1)

How should switching evaluation be conducted? Explanation using diagrams and photos.

★★Shirutoku Report: Useful Information You Should Know★★ This report introduces the switching evaluation of power semiconductors such as power devices and power modules. The ideal switching operation is a state where there is no delay time in current and voltage when switching ON/OFF, meaning there is no occurrence of power loss. However, during the switching operation of power devices, some delay time inevitably occurs. Our company has engineers with expertise in switching evaluation, so if you require evaluation of various power devices, please feel free to consult us. 【Contents】 ■ IGBT Module Measurement Circuit Examples ■ IGBT Module Measurement Environment Examples *For more details, please refer to the PDF document or feel free to contact us.

[Data] Shirutoku Report No. 65 #Power Semiconductors (2)

I will talk about a method to quantitatively verify the magnitude of circuit inductance.

★★Shirutoku Report: Useful Information You Should Know★★ In this report, we will introduce a method to quantitatively confirm the magnitude of circuit inductance. When improving the measurement environment for switching evaluation of power semiconductors, it is sometimes necessary to reconsider the wiring. However, without a quantitative understanding of the magnitude of the circuit inductance in the measurement system, improvements can be difficult. By using the measured circuit inductance values during simulations, results closer to the actual measured waveforms can be obtained. 【Contents】 ■ Methods for Improving Circuit Inductance ■ IGBT Module Measurement Circuit Example ■ How to Confirm Circuit Inductance *For more details, please refer to the PDF document or feel free to contact us.*
