square wave to triangle wave WITHOUT op amps

[mvin]

hi..is it possible to make an integrator without using an op amp implementation?or are there other ways to convert square waves to triangular waves other than using op amp integrators?i need to convert a high-power square wave to a triangular wave, and i don't think there are any op amps capable of handling 50V and 5A inputs and outputs..or at least, none that are cheap..thanks..

What about using the MOSFET linear amplifiers?

check this out.

It depends on the required accuracy.
In principle and with some errors, a simple first order lowpass (RC or RL) will do the job. By the way, an active integrator is nothing else as a first order lowpass, however with a very very low cut-off frequency.

I understand, that you want a lossless conversion of a square voltage waveform to a triangle voltage. That's impossible with a passive circuit. An inductor can integrate a square voltage, resulting in a triangular current, but without transmitting power, because the output voltage must be zero.
