Voltage control utilizing multiple PWM patterns
Abstract
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.
