• Choke coils are used in conjunction with passenger car power converters. They are mainly used in the following operations:
• Line chokes: they are used to eliminate the harmonics generated by the converter. They also protect the semiconductors in the rectifier circuit.
• Battery chargers: they are used to dampen the ripple in the output voltage of the charger, used to charge the batteries that supply power to the passenger car during power outages.
• DC Link: they are used o dampen the ripple in he voltage of the DC Link part.
• Output chokes (sinusoidal filters): used to dampen the ripple of the PWM ripple at the converter output. They also protect the semiconductors in the inverter circuit.
