Võimsushooldussüsteem

Võimsushooldussüsteem, also known as power management system, is a set of techniques and technologies designed to efficiently manage and conserve energy in electronic devices. The primary goal of a võimsushooldussüsteem is to extend the battery life of portable devices, reduce energy consumption in stationary devices, and minimize heat generation to improve performance and reliability.

The system typically includes several components, such as:

1. **Power Supply**: This component provides the necessary electrical power to the device. It can be a battery, an adapter, or a combination of both.

2. **Power Management Controller (PMC)**: The PMC is the brain of the võimsushooldussüsteem. It monitors the power supply, manages power distribution, and implements power-saving strategies.

3. **Power States**: Devices can operate in various power states, ranging from active (fully operational) to sleep (low-power) modes. The PMC decides when to transition between these states based on the device's usage and external factors.

4. **Dynamic Voltage and Frequency Scaling (DVFS)**: This technique adjusts the voltage and frequency of the device's processor to match the current workload. Lowering the voltage and frequency reduces power consumption but may also slow down performance.

5. **Wake-on-LAN and Other Wake-Up Mechanisms**: These features allow devices to be awakened from a low-power state by external triggers, such as network activity or user input.

Võimsushooldussüsteem is crucial for modern electronics, enabling longer battery life in portable devices and reducing energy costs in stationary devices. It is particularly important in the context of growing environmental concerns and the increasing demand for energy-efficient technologies.
