こんにちは。

TMDSHVRESLLCKITの現在の測定について質問があります。

「HVLLC-SWGuide [R3]」に記載されている図21の「SR電流」と図22の「タンク電流」の測定点と測定方法を教えてください。

部品を取り外さない測定方法はありますか？

よろしくお願いします。

Hello.

I have a question about current measurement of TMDSHVRES LLCKIT.

Please tell me the measurement points and measurement method of "SR Current" in Figure 21 and "Tank Current" in Figure 22 described in "HVLLC-SWGuide [R3]".

Is there a measurement method that does not remove the parts?

Thanking you in advance.

Hi user5324165,

I believe these current measurements were made by removing the transformer and adding wire loops for use with a split-core current probe.

If you do not want to remove parts from the board you may measure the voltages at the output of the current transformer / amplifier circuits (Highlighted below). For SR current I-SR1, I-SR2. For tank current, either Ipri or Ip-cs.

Alternatively, you may use a Rogowski probe like the CWT Ultra Mini. This probe will fit around one of the leads of a FET, or transformer without removing it from the board.

Best,

Clayton
