Abstract
A microelectronic device includes: a photovoltaic module configured to convert a light energy into an electric energy; a converter configured to convert a voltage output from the photovoltaic module into a predetermined voltage; a capacitor configured to store an electric energy transferred from the converter; and a controller configured to predict an available current of a next time slot based on the electric energy stored in the capacitor, and determine a consumed current of a load system of the next time slot based on the predicted available current.
Claims17
A microelectronic device, comprising:
- a converter configured to convert a voltage of an electric energy into a predetermined voltage;
- a capacitor configured to store an electric energy transferred from the converter;
- and
- a controller configured to
- measure an amount of electrical charge of the capacitor in a current time slot,
- predict an available current of a next time slot based on an output current of the converter and the measured amount of electrical charge of the capacitor in the current time slot, and
- determine a consumed current of a load system of the next time slot to match the predicted available current.
A processor-implemented power control method of a microelectronic device, the method comprising:
- measuring an amount of electrical charge of a capacitor;
- predicting an available current of a next time slot based on an output current of a converter and the measured amount of electrical charge of the capacitor, the capacitor configured to store an electric energy transferred from the converter in a current time slot;
- and
- determining a consumed current of a load system of the next time slot to match the predicted available current.
