Voltage control utilizing multiple PWM patterns
摘要
說明書
Converters 508-514 (specifically, the converter that is being commanded by one of power controllers 516 and 518 to pulse power) send power to processor 502 by pulsing during their respective PWM cycle. The power may first be routed through at least one component in order to smooth out the power delivered. For example, in some embodiments converters 508-514 may send power to processor 502 through an inductor and capacitor.
Power may be sent to the processor through voltage measurement system 520. Voltage measurement system 520 may measure the voltage of the power being delivered to the device 502. Voltage measurement system 520 may be a discrete measurement unit that is not physically incorporated into 516 or 518, or may be physically incorporated into one or both of 516 and 518. In other embodiments, voltage measurement system may be software component (e.g., an algorithm) that is part of a hardware component (e.g., one or both of power controllers 516 and 518. In some embodiments voltage measurement system may actually represent multiple voltage measurement systems. For example, in some embodiments there may be at least one voltage management system for every power controller present in the system.
