For a while (probably since I found out that switch mode power supply transformers run at different frequenciess, much higher than mains) I've wanted a device that can produce different frequencies, voltages (0-50) and wave forms so I could test high frequency transformers if I wanted to.
I know function generators exist but those seem like they put out a waveform that while precise, the unit as a whole is underpowered and under voltage for the ideas I have. Variable frequency drives exist but they won't reach the frequencies I desire and I'm pretty sure they aren't bench equipment.
Is there something I'm missing? What would a device that gives you control of the voltage, frequency and waveform but large power output be called? How can I buy/make one or does this device not exist and there some law of physics that would make such a device impractical?
