摘要

A power-delivery system may comprise a load device and a direct-current converter configured to deliver current to the load device when the direct-current converter is in an on state. The power-deliver system may comprise a voltage-measurement system configured to measure, at a beginning of each measurement cycle in a cyclic measurement pattern, a voltage at the load device. The power-deliver system may comprise a power controller configure to receive, at the beginning of each measurement cycle, the measurement of the voltage, and to perform, at the beginning of a control cycle in a cyclic control pattern, a voltage-control decision in response to a change in the measurement of the voltage being below a voltage-change threshold. The voltage-control decision may comprise whether to switch the state of the first direct-current converter. The cyclic control pattern may operate at a first frequency, and the measurement pattern may operate at a second frequency.

說明書

After shortening the PWM cycle in block 608, the voltage controller then obtains updated voltage measurements in block 602.

In some embodiments of method 600, multiple converters may be present at a phase shift that is designed to facilitate delivery of smooth power. In these embodiments, it may be beneficial to maintain the phase shift of the multiple converters when the PWM period is decreased in block 608. In these embodiments, it may be necessary to design the (or one of the) voltage controllers as a high-speed ASIC or custom PWM peripheral in order to provide greater capability for the voltage controller to recalculate phase offsets quickly.

In some embodiments of the present disclosure, a voltage decision or command to set a converter to a particular state (e.g., an “off” state or an “on” state) is disclosed. Those embodiments may include changing the converter from a prior state (e.g., off) to a new state (e.g., on). However, it is also contemplated to be consistent with the embodiments of the present disclosure for a decision or command to “set” a converter to a particular state to include maintaining the converter at that state. For example, a command for a converter to turn “on” may include maintaining the “on” state of the converter if the converter is already in the “on” state when the command is issued. Similarly, a decision for a converter to turn “off” may include maintaining the “off” state of the converter if the converter is already in the “off” state when the decision is made.
