The wave form is here.



When this waveform is input to the multiplier (Just 1 stage), it seems that the output and ripple are different for each diode.

So I thought the fast recovery diode (about 75ns to 500ns) would have good characteristics.

I used these.
US1M-HF Comchip Technology | 이산 반도체 제품 | DigiKey
-Foward Voltage : 1.65@1A; Reverse Voltage : 1000V ; trr : 75ns

CD1408-F11000 Bourns Inc. | 이산 반도체 제품 | DigiKey
-Fowar Voltage : 1.3V@1A; Reverse Voltage : 1000V ; trr : 300ns

FR1M-LTP Micro Commercial Co | 이산 반도체 제품 | DigiKey
-Foward Voltage : 1.3V@1A; Reverse Voltage : 1000V ; trr : 500ns

But all of these were not valid. The multiplier output was less than 10 volts.

The circuit is here.


Please give me some advice on the die selection.

 

The secondary is not connected right.

See red arrow.

I use 100nS or faster diodes for 60khz.

But it actually worked.

When i used this diode, S1V-13-F Diodes Incorporated | 이산 반도체 제품 | DigiKey (The datasheet does not contain trr.)
i got the output below.



Should i have to modify the circuit? I've already made a PCB board ,,

The transformer has a 67:1 turn ratio. What is the AC voltage on the Collector? The output of the transformer should be 67x more. Then there is the voltage doubler.

I didn't recorded the output of collector. What I can tell you right now is that I did not used pin1, pin5 as input. I used pin1, pin3. Isn't this why the power of the transformer is so high?

 

collector is the center leg of the transistor. What is that voltage?

The wave form is here.

Where is the 557V p-p signal?

Here is output wave of collector.


And this is the output of the transformer (open state which means there is no multiplier).

I posted below.

 

Until this problem is fixed the output will be very low.
