|Impedance link coils are used on railway lines.
They provide continuity in the return of locomotive currents and prevent faulty transmission signals at a especific frequency.
• DC Link: they are used to dampen the ripple in the voltage of the DC Link part.
• Output chokes sinusoidal filters): used to dampen the ripple of the PWM ripple at the inverter output. They also protect the semiconductors in the circuit investor.
