Three-phase inductance for sine LCL output filter - Main and secondary inductances
Three-phase inductance for sine LCL output filter - Main and secondary inductances
Description
Independent primary and secondary chokes for converter output LCL filter. They attenuate PWM switching harmonics by restoring the sine wave and at the same time eliminate the problems associated with high dV/dt.
