Hello,
I made a boost converter which was programmed with PID feedback loop. When I programmed it to boost 12V, 2.5Ah battery voltage up to 150V, the converter could not do. Even in a no load condition, the maximum voltage that the converter can do is around 107V.
My desired specification is:
1) 1mA ripple current / 10mV ripple voltage
2) 100W maximum power
3) 200V maximum output voltage
My plan is to use a flyback transformer to help stepping an output voltage up. After looking on the internet, It says that:
1) The flyback boost converter is usually use in low power applications.
2) The flyback boost converter has very high ripple current.
3) The operating frequency is specify ( I'm willing to spend time to find a suitable switching frequency)
4) Continuous current mode is not stable
Which one is more suitable for my specification?
