Hi,
I'm trying to convert a signal coming out of PIC16F877 (5V) to 60V ?
I'm trying to convert a signal coming out of PIC16F877 (5V) to 60V ?
any signal, I just need to change 5V to 60V.What "signal"?
Really, I don't knowWhat is the current you need?
I'll use an external voltage generator to generate 60V.any signal, I just need to change 5V to 60V.
This is a loaded question... 'Any Signal' is hard to do unless you attempt to build an amplifier that can amplify DC or AC.any signal, I just need to change 5V to 60V.
Really, I don't know
What frequency?it has to be like that
250hz frequency.What frequency?
i did smth like this, but it reverse the signalsYou could use a transistor, and a separate 60V source
Yes, because the transistor you used is a PNP, which requires a 'Low' signal on the base to turn on.250hz frequency.

No!
This will not work since the PNP will always be on with both
outputs of the IC(0 or 5v).
Use an NPN with inversion of the signal by the IC(if possible) like @Gryd3 suggested .
Edit: A base resistor is needed in both NPN and PNP cases.
and you need to calculate both resistors.
Put a resistor between ground and the transistor.I really can't understand what you are saying, may you draw smth to explain more
Not quite. You forgot the collector load resistor.I simulate what you draw
hrm... Maybe? I would expect it to require more parts than a pair of resistors and a transistor though...Is there any integrated circuit can do that for me ? (without the resistors, the transistors ...). coz i have more than one signal, and it kinda gonna be more complicated
I have to command a Chopper (to value a motor speed), and it works with 60VWhy a 60V signal?
Do you have any specs? Rise-Time and Fall-Time as well as current are very important... or you will have to do trial and error to see what works, and you can expect a couple parts to pop if they are chosen incorrectly.I have to command a Chopper (to value a motor speed), and it works with 60V
