@@ebaraexpress7260 Oh i forgot about that video, oops.
Please do ice3
Thank you for all your videos (and especially for the detailed explanations that accompany each one). I'm glad I'm not the only one who finds these noises interesting. Philadelphia is my home town and I spent a lot of time riding these to and from college. I always wondered why they did not have the very obvious ramping noises like the NYC M7s despite also having Mitsubishi propulsion.
Thanks for watching! Yes generally 3-level IGBTs are quieter than 2-level ones. Also I have posted other SEPTA cars, so hope you will also enjoy that!
Why is bipolar modulation used if unipolar modulation is generally superior in performance/efficiency?
patentimages.storage.googleapis.com/16/8c/08/82d1ed6e25c222/JP2006197798A.pdf P. 6 Lines 12-17 "However, the previously known unipolar modulation method cannot achieve a voltage pulse smaller than the minimum output pulse width determined by the minimum on-time of the switching device in the region where the inverter frequency is low and minute output voltage control is required (near the starting point of the VVVF control region), As shown by the dashed line in Figure 2, a voltage larger than the command will be output." In order to resolve this problem, dipolar modulation has been applied for 3-level inverters.
@@ebaraexpress7260 Oh I see, so when the train is just starting to move dipolar is used because a low voltage cannot be achieved with unipolar, then it switches to unipolar after more voltage is needed due to efficiency 👍
Could youmake a video with the CPTM 2500 and 9500 series? Thanks 🙏🏻🙇🏻♂️❤

Sound like igbt for asynchronous
That would be from the Random Carrier Frequency Modulation(RCFM) which is quite rare to find in GTO-VVVF drives, I think a few Alstom Pendolinos have it too but besides that, this might be the only GTO with RCFM to my knowledge.
Oh thanks
Is there pcfm gto vvvf

CHMPWM at different dutycycle has different flux linkage and waveform
You should record the Breda A650 (both the Westinghouse chopper control and GE GTO-VVVF versions).
This doesn’t apply to chopper. Only AC
@@QuarioQuario54321 That’s incorrect. The chopper generates a PWM frequency that can be picked up by an inductor. Resistance/cam control cannot be recorded because it is changing the voltage with resistors rather than using PWM.
収録お疲れ様です。GTOでガッツリランダム変調とは珍しいVVVFですね。
Love it. Is there any chance of you catching a video of the Bombardier M7 IGBT VVVF sound as well?
I tried 5 years ago, however failed to get the ideal sound (smooth transition from async to 1P with less noise). Instead, you can refer to this video posted by other creator: ruclips.net/video/gpLRxpE3gSs/видео.html
Half of it sounds like a R160
やっぱ最初のは急上昇タイプだったんですね。同期モードが聞こえにくいから1Pオンリーかと思いきや…。 Type2っぽいのはC編成でよく見かけましたね〜
Fantastic video as always! This is perhaps going to sound silly but I've been having issues recording certain stock while accelerating due to transient noises like those that can be heard starting around 0:18 and I was curious if you had any info or theories as to what is causing those noises?
Thank you! That kind of noise might be caused by contact between wheels and a rail, or if that train is running in a third rail section, then that should be caused by the rubbing between the contact shoe and the conductor rail.
The waveform of the dipolar part in type 1 looks more like 250Hz and 50% dipolar rate (quadruple).
Maybe that is because you see lines around 2700Hz and 3300 Hz, but they are from input AC side (there was a bold line around 3000 Hz so I reduced by a notch filter, however these edge components are still remaining here) and not from the inverter. Also, if that kind of modulation you mentioned is applied, there should be components for 750 Hz and 1250 Hz, but not visible here. Moreover, Mitsubishi hadn't used that kind of modulation until late 2000s. Therefore, I think this is 500 Hz with 70 % dipolar rate.
@@ebaraexpress7260 The pulses in the waveform (not the spectrum) seems to be equally spaced, but the pulses in the twice frequency bipolar mode occur in pairs, so it is suspected to be a 250Hz quadruple dipolar mode.
@@CR400AF-B When determining a PWM mode, we rely more on the spectrum than on the waveform. Since we cannot remove noise components from the displayed waveform results, it is difficult to judge the mode. Also, there are some cases that inductor recorded data is more like a phase current than line-to-line voltage, which causes confusion for judging the mode; on the other hand by spectrum we can judge from both phase current and line-to-line voltage, since they are showing similar results: yuppi5.hateblo.jp/entry/pwm2 So, for this case, since I give more weight to the fact that there is no 750 Hz and 1250 Hz spectrum shown, let me conclude this as 500 Hz. Anyway I'm so interested in the way you guessed.
@@ebaraexpress7260 Your analysis is reasonable. From the spectrum, it looks more like the E2 series, and 500Hz is also a reasonable switching frequency for 3300V IGBT devices during motor start-up. Indeed, when doing moharadio on many China high-speed trains, the superposition of multiphase currents and noise makes it difficult for me to see the waveform clearly.
😌
😮
Apologies, regarding the Type 2's braking data, the correct switching timing for 1P → multi-pulse is at 9:46. Type 2の減速時における1P→同期多パルスの切替タイミングは正しくは9:46になります、ご承知おきください。
Some Toshiba 2-level IGBTs also have a similar asynchronous pattern, but the only difference is that in the first part, there is an increase in frequency change instead of a constant → increase frequency change.

If you are mentioning the pulse mode after async, that is not W3P, maybe a type of 5P.
Could it be HOP-5?
@@dabee1884 It's possible. I think some newer Hitachi inverters use it.
@@dabee1884 Since HOP is more a recent development, and has different waveform, I guess this is other type of 5P.

Isn't 1 pulse per half cycle very harsh on the motor?
I have always wanted to know, on these trains, when the pitch increases where it still sounds like it is carrier frequency based (25 mph on overhead / 15 mph on 3rd rail) does the VF drive lock the carrier, so effectively turn the carrier into a fixed pattern, or does the drive casually increase the carrier, making it sound a bit like a locked pattern, but is actually still a carrier?
Carrier-sync modulation I believe
i THINK the pulses are still widening AND the carrier is increasing. it's not as obvious on this particular spectrogram trace, but i've seen others where the two diverging frequency lines on the graph that represent the carrier widen out way quicker while still increasing. at least until it goes FULLY synchronous, then i t looks and sounds like the pattern is locked. it's a weird hybrid of async and sync that i keep seeing more and more on these spectrogram vids, mostly on vf drives of Japanese make. they always seem to be the ones that innovate this tech i'm also pretty sure that they were the first ones to implement a random carrier, at least as far as i'm aware, which i find fascinating. i have a small 1/4hp Fuji Electric vf drive at home that lets you select three levels of carrier scrambling! it's not truly random but it has the same effect of making a buzzing sound instead of a constant ringing
It slowly increases the carrier frequency but it is not synced to the output frequency. I recorded the Osaka Metro 20 Series with the replacement inverters and they also sound similar to this.
Nice to see a UK train on here.
