CONVERTERS FOR PASSENGER CARS
Statical converter M-ÏÒÅ-22-Ó1
Statical converter is designed for complete set of passenger cars electric equipment with self-contained power supply and air conditioning, and is used for providing supply of conditioning installation electric engines, just: compressor electric engine and fans ones.
Converter composition
Converter consists of input switching-and-protective equipment, three input increasing constant voltage converters, three three-phases invertors, three output filters, output protective equipment, control one, parameters control and diagnostics, signalling.

Design
All converter equipment is disposed in the sealed container, which is installed in the under-coaching surface.
Overall dimensions of container (length x depth x height), mm – 1900 x 700 x 700.
Mass, not over, kg – 400.
Converter has block-and-module design with use of IGBT – transistors and microprocessor CÓ, adopted for appraisal of separates elements (units) current state with built-in and external diagnostics facilities. Converter is made by natural air cooling with running on air flow during coaches (cars) motion. Converter is made in climatic version Ó, siting category 1.
Service conditions
- upper value of maximum ambient air operating temperature +45 C;
- low value of maximum ambient air operating temperature -50 C;
- height above sea level, not over than 1400 m;
- in the part of mechanic environmental factors influence - group M25, within value of single impacts – 5 q.
