CONVERTING TRANSFORMERS

Utility and characteristics	Upon request	Materials and constructions	Certificates

• 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.	RTR Energía’s technical department offers the possibility of manufacturing equipment according to the client’s application needs.	• Grain oriented silicon steel core. • High quality copper or aluminum windings. • Class H insulation. • Impregnated in a special epoxy varnish that gives it immunity against environmental effects such as humidity, dust, etc.	• IEC 60310 • UNE-EN 60310
