The application for the patent was published on May 29, under issue no. 22/2026.
According to the abstract released by the Intellectual Property India: "Electric Vehicles (EVs) require efficient power management systems to supply different voltage levels for various auxiliary components such as lighting, sensors, electronic control units, and communication systems. Conventional EV architectures use multiple individual DC-DC converters to meet these requirements, which increases system complexity, cost, and power losses. This project presents the design and development of a multi-output DC-DC converter capable of generating multiple regulated voltage outputs (24V, 12V, and 5V) from a single high-voltage DC source (48V battery). The proposed system utilizes power electronic components such as MOSFETs, inductors, capacitors, and diodes along with closed-loop PWM control to ensure stable voltage regulation under varying load conditions. In addition, the system integrates sensing and protection mechanisms to detect over-voltage, over-current, and temperature variations, thereby enhancing safety and reliability. An IoT-based monitoring system using ESP8266 enables real-time data visualization and remote control of auxiliary outputs. The system is implemented and tested under different operating conditions, and the results demonstrate stable output voltages with good regulation (within 2%) and improved efficiency of approximately 92%. Compared to conventional multi-converter systems, the proposed design reduces component count, system size, and overall cost while improving performance. Hence, the developed multi-output DC-DC converter is highly suitable for modern EV auxiliary power applications, offering a compact, efficient, and intelligent power management solution."
