Hi friends,
I wish (actually a client does) to recover the energy of some consecutive pulses and I have only come up two half-baked ideas so far, so let me know what you think.
Here's the pulse given, measured over a restive load.
The x-axis is time in nano-seconds.
These are the constraints given:
1. The pulse amplitude and frequency can vary +/- 20% from pulse to pulse
2. The resistive load is limited to about 2 ohms
3. If required, the pulse can be made short as a few microseconds or stretched to about 300 microseconds. The average power remains the same regardless of pulse length.
I have calculated the average power to be 478KW for that particular pulse. I think that's a lot of power to recover, so my best idea is simply to dump the pulse(s) into a resistive heating element and boil some water. There is not an objection to hot water as such, but they would have better use if it could be converted into a more practical dc voltage. For the dc voltage option, my best idea is an air-core transformer - but I'm not sure how efficient that would be compared to boiling water?
