2x500 kVA IGBT based Hotel Load Converter has been designed for WAP-7 class of three phase passenger Locomotives, of Indian Railways.

State-of-the-art technology Power modules & latest Digital control electronics have been used in design and manufacturing of this Hotel load converter. The system serves to convert single phase line voltage of 960VRMS fed from Loco transfer into 750VRMS three phase power. This output power is used for various loads viz. Air conditioning, utility, Pantry etc. called as "Hotel Load" of the locomotive.

Each 500kVA converter contains Front End Converter. Three Phase inverter is designed with 3 Level NPC Topology. Benefit of using 3L Topology is utilization of Lower Breakdown Voltage IGBT Modules & Lower current THD. Use of devices with lower breakdown voltage produce Lower Power Loss thereby improving efficiency and possibility of incorporating force air cooling system.
