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.

摘要： An analog closed-loop, negative feedback system that adapts feedback compensation during operation thereof to improve dynamic performance thereof. Using a pure analog control loop with digital assist provides speed and simplicity of an analog control loop with the flexibility of digital control. Adapting the compensation allows the system to accurately predict and adjust, at all DC operating points, (1) the margin of stability of the converter, against closed loop oscillation, and (2) the frequency-domain and time-domain responses to perturbations in the input voltage and/or the output current. Operational transconductance amplifiers (OTAs) and digitally controlled digital-to-analog converters (IDACs) are used to dynamically change the operating parameters of the analog closed-loop of the negative feedback system. The negative feedback system may be a switch mode power supply (SMPS).
