hi guys i was hoping you might be able to help me i want to achieve from 12vdc in 180vdc out but i need it so that the voltage level a micro controller can alter the voltage level if you could help i would be greatful
hi thanks for your reply i need to suply at least 6 amps dc to the rest of the circuit which is a type metal detector iam working on
so i am bit unsure on dc to dc converters especially setup boost converters and there power and voltage transformation ratio are like especially something that would deliver 12vdc in and 180vdc outAt 180VDC, this works out to 1080 watts.
This means your 12V supply must provide 90 A. Add 20 percent for losses. Say 110 A.
Rather than a single converter, it could work better if you interleave several boost converters.
There are metal detector designs which run on less power, just a few small batteries.
What about just paralleling full bridge converters till each has a manageable current.
Then adjust your vout by having an external error amplifier(s) driving the pwm chip.....make the reference voltage into the external error amplifier variable , commanded by the micro, that will give you vout variation.
