Specification
Description:Background:
Electric vehicles face challenges with power efficiency and battery longevity. Power converters that manage energy between the battery and motor systems are crucial for extending driving range and performance. This invention improves upon conventional converters with advanced control mechanisms and phase management.
Technical Description:
1. Converter Architecture:
o DC-DC Converter: Efficiently steps down the high-voltage battery to a lower voltage for motor operation.
o AC-DC Inverter: Converts DC to AC for brushless motors in EVs, providing controlled power.
o Multi-phase Configuration: Utilizes multiple interleaved phases to reduce ripple and heat, allowing smoother energy flow and reduced component stress.
2. Intelligent Control System:
o PWM Modulation: Adaptive Pulse Width Modulation (PWM) to adjust output frequency and reduce switching losses.
o Feedback Mechanism: Real-time feedback to control voltage and current levels, optimizing performance based on load requirements.
o Battery Protection: Monitors battery health metrics, avoiding overcharge and deep discharge cycles.
3. Thermal Management:
Integrated cooling fins and temperature sensors to maintain converter temperature within safe operating limits.
, Claims:Claims:
1. A multi-phase power converter designed for electric vehicles to improve energy efficiency and power management.
2. Adaptive PWM for real-time optimization of switching frequency and reduction of power losses.
3. Intelligent control systems that provide feedback for enhanced battery management and protection.
4. A thermal management system integrated with temperature sensors and cooling elements.
