摘要： A control circuitry can be configured to receive an error signal indicating a difference between an output voltage of the power supply and a desired setpoint for the output voltage. According to one configuration, depending on the error signal, the control circuitry initiates switching between operating the control circuitry in a pulse width modulation mode and operating the control circuitry in a pulse frequency modulation mode to produce an output voltage. Operation of the control circuitry in the pulse frequency modulation mode during a transient condition, such as when a dynamic load instantaneously requires a different amount of current, enables the power supply to satisfy current consumption by the dynamic load. Subsequent to the transient condition, the control circuitry switches back to operation in the pulse width modulation mode.

摘要： According to one configuration, a monitor circuit monitors a delivery of power supplied by one or more switch devices to a dynamic load. Based on an amount of power delivered to the load as measured by the monitor circuit, a control circuit produces a voltage control signal. A gate bias voltage generator circuit utilizes the voltage control signal to generate a switch activation voltage or bias voltage. A switch drive circuit uses the switch activation voltage as generated by the bias voltage generator to activate each of the one or more switch devices during a portion of a switching cycle when a respective switch device is in an ON state, and the respective switch device conducts current from a voltage source through the switch device to the load. The control circuit adjusts the voltage control signal to modify a level of the switch activation voltage depending on the dynamic load.

摘要： According to example configurations as described herein, a power supply system includes a unique circuit including an analog summer circuit, an analog-to-digital converter, and a digital controller. An output voltage feedback control loop of the power supply system feeds back the output voltage to the analog summer circuit. The analog summer circuit generates an analog error voltage signal based on: i) the output voltage received from the output voltage feedback loop, ii) an analog reference voltage signal, and iii) an analog reference voltage adjustment signal. The analog reference voltage adjustment signal varies depending on a magnitude of current provided by the output voltage to the dynamic load. Accordingly, the analog summer circuit can be configured to support adaptive voltage positioning. The analog-to-digital converter converts the analog error voltage signal into a digital error voltage signal. A controller generates output voltage control signal(s) based on the digital error voltage signal.

摘要： A power supply system includes a PID control circuit, a signal shaping circuit, and a PWM control circuit. The PID control circuit generates a signal based on an error voltage of the power supply system. The signal shaping circuit receives and converts the signal outputted from the PID control circuit into a linear control signal. To reduce cost, the shaping circuit can include a piecewise linear implementation. During non-transient load conditions, the PWM control circuit utilizes the linear control signal outputted from the signal shaping circuit to adjust a switching period of a power supply control signal. The switching period of the power supply control signal is maintained within a desired range. During transients, settings of the PID control circuit are modified to provide a faster response. The switching period of the power supply control signal may be adjusted outside of the desired frequency range.

摘要： According to example configurations herein, a controller receives a value indicative of a number of phases in a power supply to be activated for producing an output voltage to power a load. The controller utilizes the value to adjust a magnitude of at least one control coefficient associated with the power supply. The control can also use the value of the input voltage to adjust the magnitude of at least one control coefficient. For example, according to one example configuration, the controller digitally computes values for the one or more control coefficients based on the received value indicating the number of phases in the power supply to be activated for producing the output voltage. Based on the adjusted magnitude of the at least one control coefficient, the controller produces control signals to control the number of phases in the power supply as specified by the value to produce the output voltage.

摘要： According to example configurations herein, a controller receives a value indicative of a number of phases in a power supply to be activated for producing an output voltage to power a load. A resonant frequency of the power supply changes depending on the number of phases activated. According to one configuration, a controller utilizes the value to proportionally adjust at least one control parameter associated with the power supply in accordance with a change in the resonant frequency. In addition to modifying a parameter based on the number of activated phases and/or the resonant frequency of the power supply, the controller can also use the value of the input voltage as a basis to adjust at least one control parameter. Moreover, according to one example configuration, the controller digitally computes values for the at least one control parameter based on a number of phases to be activated.
