Dear All,
I need to make a high-voltage pulse generator system. The broad topology I found from literature is H-Bridge with a series resonant circuit. The commercial system has waveforms as follows.
I have developed H-Bridge with Transformer (having 1:20 Turns ratio) Primary inductance as 227uH and Leakage 27uH.
When using series resonant circuit of (L-C, 220uH, 30nF) the following waveform is obtained at 150V DC
However, the Output Voltage gain is lesser
When I am using Leakage inductance of the transformer along with C value of 440nF. I am getting appropriate boosting. However, I am not sure if its in resonance.
The rate of rise is sudden in this case.
The switching frequency of the Inverter is 60kHz.
What would be the right design of resonant circuit to get nearly similar waveforms as in first in image.
Also please let me know if any other references /design article for the same.
Thanking you.
