摘要： The present invention pertains to calibration in current sensing applications. Power conversion systems such as those used in computer architectures may employ step down converters such as buck converters or other types of converters. The present invention provides calibration processes and devices to account for various parasitic resistances which are found in such systems. A calibration circuit may be coupled to the buck converter or other power conversion to determine a calibrated voltage signal for the output of the power converter. An effective DC resistance may be determined and programmed for use by a control device used. In this way, the parasitic resistances are taken into account to obtain an accurate estimate of the actual current. In turn, this enables power converters and other devices to operate within specification requirements.

摘要： Aspects of the invention pertain to optimization of voltage converter efficiency for all load conditions. A signal conditioning circuit is electrically connected to a number of buck converter modules that supply power to different loads. Each module includes a voltage regulator module, which issues a signal that is proportional for its respective load current. The signal conditioning circuit integrates and averages the signals from each voltage regulator module to produce a conditioned voltage signal. The conditioned signal drives a controller, which in turn provides control information to a power conversion circuit. Operation of the signal conditioning circuit cause the controller and power conversion circuit to adapt the driver voltage of the buck converter modules, which improves and optimizes efficiency for all loads.

摘要： Embodiments of a circuit, which includes a device and a switch, which is electrically coupled to the device, to control power applied to the device, are described. This switch includes a control terminal, which controls the switch, and two other terminals, which can receive power to be applied to the device. Moreover, the circuit is configured to apply a voltage to the control terminal to ensure the switch remains open when a supply voltage is applied to one of the two other terminals while powering-up the circuit, thereby preventing spurious application of the supply voltage to the device.
