Computing device

Abstract

A power control unit is disclosed, comprising at least one power supply terminal for connection to a power supply, at least one load terminal for connection to a load, an electrical current path configured to connect the at least one power supply terminal to the at least one load terminal, a plurality of switches connected in series along the electrical current path, and control logic configured to determine a level of electrical power to be distributed from the power supply terminal to the load. The control logic is configured to distribute the determined level of electrical power to the load by pulse width and/or pulse frequency modulation, by independently controlling each of the switches to transition between an open-circuit state and a closed-circuit state to control the width and/or frequency of pulses supplied to the load. The power control unit may be included in an aerosol provision device. A method of operating control logic for a power control unit is also disclosed.
