摘要： Hysteretic performance with fixed frequency may be achieved in controlling a power/voltage regulator, by adapting fixed frequency PWM (Pulse Width Modulation) to current-mode hysteretic control. In steady state, the current waveform may be inferred without having to measure the current. In current-mode control, the current may be adjusted proportional to the error voltage. The change in load current may be related to the change in duty-cycle, and the change in duty-cycle may be related to the error voltage, with the change in duty-cycle expressed as a function of the error voltage, to establish current-mode control. This current-mode control may be adapted to perform current-mode hysteretic, if instead of duty-cycle, the same duty-cycle or current shift was effected by a change in phase. A fraction of ripple current (Forc) may be defined as a specified fraction of the peak-to-peak ripple current, establishing a linear relationship between the Forc and the ripple current.
摘要翻译：通过使固定频率PWM（脉冲宽度调制）适应当前模式的迟滞控制，可以在控制电源/电压调节器时实现具有固定频率的滞后性能。在稳定状态下，可以推断电流波形，而无需测量电流。在电流模式控制中，电流可以与误差电压成正比。负载电流的变化可能与占空比的变化有关，占空比的变化可能与误差电压有关，占空比的变化表示为误差电压的函数，以建立电流模式控制。该电流模式控制可以适于执行电流模式滞后，如果代替占空比，相位的变化实现相同的占空比或电流偏移。纹波电流（Forc）的一小部分可以定义为峰 - 峰纹波电流的指定分数，建立Forc和纹波电流之间的线性关系。

摘要： A method for optimizing operation of a feedback system may include generating a control signal according to a control parameter, regulating an output of the feedback system via the control signal, and monitoring the control parameter. In response to the monitoring indicating that the present value of the control parameter is outside a specific range of values, a first parameter that impacts an operating characteristic of the feedback system may be adjusted until the present value of the control parameter is within the specific range of values. The specific range of values of the control parameter may correspond to a target level of the operating characteristic of the feedback system with respect to the first parameter. One or more additional independent parameters also impacting the operating characteristic of the system may be similarly adjusted to obtain a minimum present value of the control parameter at which the output of the feedback system would be regulated, with the minimum value of the control parameter corresponding to the target level of the operating characteristic of the feedback system with respect to, collectively, the first parameter and the one or more additional independent parameters.

摘要： A circuit that efficiently prevents the turning on of the synchronous rectifier in a buck converter during a predetermined condition, so as to prevent current reversing through the synchronous rectifier during that time. In one embodiment, the circuit provides control of the synchronous rectifier during the soft-start time for a non-isolated DC-DC buck converter, thereby preventing current reversing (sinking), referred to as the back bias condition, during its soft start process. In another embodiment, a circuit uses a signal indicative of a soft-start condition for a converter to prevent the turning on of the synchronous rectifier during the soft-start time. A corresponding system solves the aforementioned synchronous rectifier back bias problem for converters used in a paralleled converter configuration.

摘要： A feedback control system, e.g. a voltage regulator, may include a control stage controlling an output stage that generates an output. The control stage may generate a control signal, e.g. a pulse-width modulated signal, having a duty-cycle and a switching frequency, and adjust the switching frequency when a present value of the duty-cycle differs from a most recent previous value of the duty-cycle, until the duty-cycle starts increasing, while also adjusting the duty-cycle according to the output. By adjusting the switching frequency, the (power) efficiency of the system may be optimized also regulating the output. The feedback system may also adjust the switching frequency according to an alternate algorithm to improve but not necessarily optimize the power efficiency by scaling a programmed frequency value using a scaling factor that is a function of a maximum duty-cycle value, a present frequency value, the programmed frequency value, and a minimum frequency value.

摘要： A single-cycle charge regulator (SCCR) may be used in operating a power converter at a constant frequency without requiring compensation. The SCCR may include a first control loop to generate an error value based on the output voltage of the power converter and a reference voltage, and to generate a first control value based on the error value to control steady-state behavior of the output of the power converter. A second control loop may generate a second control value based on the error value, to regulate response of the power converter to a transient deviation on the output voltage. A third control loop may operate to adjust a current (affected by the output voltage of the the power converter) subsequent to the transient deviation, according to a third control value derived from previous values of the first control value, the second control value, and the third control value, to keep the adjusted current commensurate with the current that was present prior to the transient deviation, while keeping the output voltage of the power converter at its desired steady-state value.

摘要： Complex filters may be used to achieve compensation of a plant, corresponding for example to a power regulator or point-of-load (POL) regulator. Digital filter coefficients may be mapped to analogous poles and zeros, or they may be mapped to values of the quality factor (Q) of the output, frequency, and gain. The plant may be observed and characterized using a network analyzer to generate the Bode plot (or Nyquist plot) for the plant. The digital filter coefficients may be mapped to features that may be identified on the Bode plot (or Nyquist plot) to easily correlate characteristics of the digital filter or digital compensator to the plant characteristics. The mapped features may be adjusted, for example by a user, either manually or by executing one or more optimization algorithms, to achieve the desired results relative to the Bode plot (or Nyquist plot). The mapped features may then be reverse mapped to the digital filter or digital compensator coefficients to fine tune and implement the digital filter or digital compensator.
