RELATIVE EFFICIENCY MEASUREMENT IN A PULSE WIDTH MODULATION SYSTEM |
摘要 |
A pulse width modulation (PWM) power conversion system has improved efficiency over a wide operating input voltage and load range. Being able to measure relative efficiency of an analog PWM system allows enhanced control while maintaining the benefits of analog control. An analog low pass filter produces an average value of the PWM pulse train, then this analog average value is converted into digital values with an analog-to-digital converter and stored so that relative efficiencies of the PWM power conversion system may be compared for various combinations of operating parameters. |
