Driver circuit for a few kW three-phase induction motor
A single phase is generated by an operational amplifier that amplifies to saturation the difference between the foundamental and a triangle wave m-times faster (both low power signal form a variable frequency oscillator). m has a crucial impact on the quality of the final power signal, in three-phase systems like here it's usually a multiple of 3. I've chosen 21.
L=2µH, C=4.7mF, R= 27.5mΩ, G=1GΩ
