Tracel Industrial Battery
Charging Rectifier
recT Product Line
The recT line battery chargers/rectifiers are electric power conversion equipment used mainly in substations in generation, transmission and energy distribution sectors.
These rectifiers were 100% developed by Tracel with the following characteristics:
- IGBT technology with 12-pulse rectification;
- Peak power factor and efficiency;
- High grid and M-G set input harmonic distortion tolerance;
- Densely integrated control, supervisor and monitoring unit, with HMI and fewer electronic component boards;
- Special projects according to the customer’s request.
Tracel has been exceeding expectations in the domestic market with its unique patented technology, with imported power components we build the charging battery rectifier that meets client demands. Each unit is composed of the following subsystems:
Isolating Transformer: traditional (with grain-oriented cores and copper wiring) or special high-frequency transformers with low loss ferrite material, and little to no noise coupling between the primary and secondary.
Formidable output inductor with a unique magnetic core that greatly reduces inductor size and used copper material.
Power Module: Input rectifying bridge design, precise capacitor and switch selection, and custom cooling and heat sink projects through mathematical modeling of thermal losses in switches, diodes, and other components; advanced simulations and trial testing validation.
Diode bias module: Bypass Diode and relay design,validated through thermal loss calculation from power components; advanced simulations and trial testing validation that complement component selection, according to the cooling and heat sink configuration.
Control Module: Electronic circuit board design, consisting of specification analysis, computer simulation, and electronic board routing*¹, electronic component mounting, and application-specific software development involving low-level programming of advanced microcontrollers and digital signal processors.
Electrical and mechanical projects that have integrated all industrialized Tracel equipment/components developed through CAD software, and physical mounting and testing.
