Power systems provide the energy required to run electronic circuits and devices. They include energy storage, harvesting, and regulation components.
Power systems can be understood through several key conceptual components:
Energy Storage: Batteries and other systems store energy in chemical or physical forms and convert it into electrical power when needed.
Power Generation: Devices like solar panels and piezoelectric systems harvest energy from the environment to generate electricity, enabling renewable or self-powered electronics.
Power Regulation: Voltage regulators and converters ensure that the electrical power delivered to a circuit is stable and within required parameters. Consumer electronics primarily rely on direct current (DC) power, often derived from alternating current (AC) sources via adapters or chargers, ensuring compatibility with home and industrial power grids.
