I really enjoy these pulse laser videos, especially the flash lamp trigger circuit details. Thanks for taking the time to break this down.

Where is the circuit diagram and how far can it reach?

Really pretty but shame for the tube. It looks like there is welding going inside of the tube haha

Of course, driving the gate and discharge of a MOSFET is very difficult.

That's so cool mate 😍😎

Wait, what do you mean by pwm modulated?😮

That is very interesting. I am not even into engines but stuff like this also gets me excited! (i cant wait to see you doing rf tube stuff again) haha

Sorry for the audio condition, at the time I was making the video the phone should be overheated.

Is there salt on the electrode?

Good job! What about the bandwidth of this switchmode amplifier? i.e. what is the top and bottom frequency between it perform like a class E amplifier, without retuning components?Thanks for share your knowledge!

Very nice video and explanation. Thank you.

I did not know you uploaded this!

110V, 9A and just (nearly) touching the drain of his mosfet #deadwish

😎

Thanks You, your work is very helpful for me

how much mhz this ?

Good demonstration, thank you

What magnetron were you running when you damaged you camera? XD Must've been quite a high peak power

No safety

Why not covered?

It’s frightening to see that scary RF candle near your laptop

Hi guy, what is your mosfet?

good day just seeing your video and I am interested in making this stuff. thanks for sharing.

Hi guy, how much is the power of input signal ?

Art of power!! What did you do as improving the gate?

Amazing. A fully functional HFVTTC with not a single doorknob capacitor in sight :D I guess all the tank capacitance just consists of the parasitics in the coils and tube, right? Very cool, as usual

Вот это уже больше похоже на факельник А то 5 см разряд это максимум свечальник)

Ive also tried exciting one of those induction lamps with a class E oscillator (HFSSTC without matching coil, just like yours!). Those induction lamps are extremely easy to induce ICP in, which makes sense given that it's what they're designed for XD

Could you drop me pls this solidworks sketch? Much appreciated

Hi guy, does it run on ICP plasma tube?

Hi, thanks for your nice videos, could you please share your schematic? I need atleast 200w hfsstc to run my inductively coupled plasma tube.

What an interesting project for postgraduates. It has happened to me that in Chile I have met researchers who only work below 1 MHz; while others only over 10 GHz. What was the project about? any paper to read? Greetings.

The BLF188 truly is a great device, very tolerant of vswr mismatches. I have used them at HF frequencies and also VHF but not as yet on higher frequencies. I have not managed to blow one, despite antenna accidents. This is the first time I have seen this chip used in a class E configuration. From your comments below I calculate the efficiency to be around 80% This seems a little on the low side. I don't see any vias along the transmission line ground planes, could this lower the efficiency? I always silver plate when working above VHF and this does make a difference. I too would like to experiment with class E and will be building a test circuit. I once saw a data sheet that suggested these chips for not really suitable for class E, I am not sure why that was the case, the only concern is a carefully controlled gate voltage swing. (EDIT, just while writing this, I remember the reason - Drain voltage swing, VDD x 4 ish for class E. Compared to VDD x 2 ish for AB.) What are your thoughts on the drain voltage problem? Great work building the amp and thanks for posting. Chris, UK.

Ha thats awesome 😎

Wow super cool i am trying to build hfsstc brother can you help me building it

I got a plasma light source, originally used as a medical instrument. Can be coupled to glass fiber and used in an operation. Power is like 250W at UHF frequency. Will do a detailed teardown in the coming month when I have enough time for it.

VERY HELPFUL .. THANKS A MILLION

Get it running!

could you possibly post a video of it running? my curiosity has peaked on how it sounds.

Man that's tiny

Would lovw to see it running !
