Hello
I designed the motor driver using the IC controller IMC102 and switch IFCM15P60GD for the motor PMSM with Power 750W, and in practical testing, at the time of connecting the AC input and in some cases during the operation Short ciruit between pin collector to emitter in IFCM15P60GD (Pin 22 , 23) and it fail ,
The diode that I put on the fiber in parallel with the body diode of the switch PFC is part number BYG20J ,Is my choice correct? Can it be the cause of damage to the PFC switch or may it be another reason?
board specifications
Input Voltage 165 - 265 Vrms AC input
Input current 3 Arms input 220 VAC, IFCM15P60GD
Current per leg 2.1 Arms input 220VAC
DC bus voltage 400 V
PFC switching frequency 50 kHz
Inverter switching frequency 15 kHz
PFC current sensing resistor 25 mΩ
Inverter current sensing resistor 50mΩ (Single Shunt)
What solution do you suggest?
Best Regards.

DIP 36x21D packageの上面の放熱プレートは内部と絶縁されておりますでしょうか。
実装する際に絶縁シートが必要かあるかご教示いただきたいです。
下記のANではサーマルグリスを介してヒートシンクとなっておりますがサーマルグリスに関しては絶縁、非絶縁の記載が見当たらなかったためご教示いただきたいです。
以上です、よろしくお願いいたします。

Hello,
I am interested in using IRSM808-204MH in a new product design. The datasheet is not clear about a few things.
1. How is the "DT" (dead time) pin supposed to be used? What do you connect it to, and how does that control the dead-time?
2. Is the part fully protected from a Shoot Through condition? The truth table shows "Shoot Through" but does not explain if the part is protected from damage in this condition.
3. What is the maximum switching frequency of this part?
Please advise, thanks.

Hello,
What is the IR3575MPBF and IR3564BMTRBF fit value and MTBF value?
Hi,
I selected IMX828 device for the application of DC_DC converter front end converter.
Planned to operate it at frequency of 80kHz @ 15V Vdd.
How much wattage power supply required for the Vdd.
Also what will be the power consumption of the complete IPM IMX828.
Suggest for the suitable calculations to use the IPM with my 4kW dc-dc converter ( Input : 500V & Output : 12V )
Show LessHi all,
it is first time using IRSM005-800MH .
I encountered some trouble.
I have circuit like below.
what I'm expecting is high side FET turn on. and to see V_LOAD : 35V. with V_HGATE=50(=35+15)V
but , high side is not turned on at all. V_LOAD : 0V, with V_HGATE=0V.
I'm afraid , I'm taking something wrong using this device.
My purpose is just to use this device as high side load switch.
please help me.
what I found is V_HGATE just follows VS level. no boost-up to enable gate of the FET. whether HIN is enabled or not.

正常参考数据手册真值表,设计驱动端程序。芯片无法正常工作,表现在三相单元无输出。检查EN及ITRIP引脚状态正常,希望有用过相同芯片的朋友能帮忙解惑。
程序设计思路,HA :1 LA :0 HB:0 LB:1 内部MOS管导通方式为 A+,B- A端可以测到电源电压。如果把电机接进去 电机应该有抖动。
类似的方法,驱动别的MOS管。希望有使用经验的朋友帮忙解答下。

Does the header have a 2.54mm pitch?
