Triphase to make parts for EV power management systems
Triphase Technologies Pvt Ltd, an Original Design Manufacturer for the OEMs, is working on e-mobility solutions like chargers, DC-DC converters and BLDC motor drives. The company supplies power conversion and control solutions to leading OEMs in the field of IT, telecommunications, automotive, railways, lighting and energy management.
“In electric vehicle (EV) space we are focusing mainly on chargers, converters, battery management system and motor drives. We develop intelligent on-board charging systems where there is CAN communication to help communicating with the electronic systems in the car. DC-DC converter takes the battery voltage on the vehicle and converts into 12V DC which is required by the sub-systems in the electric vehicle. Motor drives the controllers which drive the motor of the vehicle,” Shyam M Gopinath, Director, Triphase Technologies Pvt. Ltd, told Auto Components India.
Along with the increasing number of electric and hybrid vehicles, the demand for charging stations will surge. For speedy charging, both the vehicle types will need highly-efficient on-board AC/DC chargers with high-power density and suit the space and weight parameters. Triphase is working on an onboard charger which can control the values of the load voltage and current and maintain them at a desirable value, he said.
DC-DC converter supplies conventional low-power, lowvoltage loads. However, the need for high power bidirectional DC- DC converters in future electric vehicles has led to the development of many new topologies. Motor drive system is one of the core components of electric vehicles. To meet the electric vehicles performance requirements like starting, accelerating, climbing and other driving conditions, motor drive system requires high torque at low speed, high power at high speed, wide speed control range, etc.
“We develop Battery Management Systems based on customer requirement. Battery packs are normally connected in series and parallel. Together with Renesas Semiconductor, our solution monitors individual cells. Up to 16 slave devices are monitored on 1 master device. Our products are designed and manufactured in India using world-class technology. While being cost effective, we also ensure that the products are rugged and suitable for Indian conditions. Single Phase On-Board Chargers are up to 3.3 kW, while 3 Phase Chargers can be up to 10kW. Raw Materials are procured from major semiconductor manufacturers like Renesas, Infineon and Nichicon. All these companies are global players with plants across the world. We do have the technology and solutions for DC fast charging using solar and wind energy. Large players and OEMs are yet to set up fast charging stations across the country which will be essential to make EVs viable. Triphase has started discussing possibilities on this front with some large corporates,” Gopinath said.
Triphase has manufacturing facilities in Bangalore and at Parwanoo, in Himachal Pradesh, which are fully equipped to offer EV products to the major OEMs in 2W, 3W and 4W segment. The present supplies are in limited numbers as the EVs are yet to take off. The company has 3 SMT Lines and 4 Through Hole Soldering Lines to ensure timely delivery.
“To ensure that we are at par with the changing customer requirements and market, we have developed an in-house research and development unit. It is managed by an efficient and talented team of researchers and engineers who conduct research on new designs in our range. Through on-going efforts in the R&D unit, we improve level of services and quality of products,” Gopinath said.
