lülitusregulaatoriteks

Lülitusregulaatoriteks is an Estonian term that translates to "switching regulators" in English. These are a type of DC-to-DC power converter that efficiently regulates voltage. Unlike linear regulators, which dissipate excess energy as heat, switching regulators use an active semiconductor switch, such as a transistor, to rapidly turn the input voltage on and off. This switching action, controlled by an inductor and capacitor, effectively changes the output voltage to a desired level.

The core principle of operation involves storing energy in an inductor when the switch is on and releasing it to the output when the switch is off. By varying the duty cycle, which is the ratio of on-time to the total switching period, the output voltage can be precisely controlled. This makes them highly efficient, especially when there is a significant difference between the input and output voltages.

There are several common types of switching regulators, including buck converters (step-down), boost converters (step-up), and buck-boost converters (which can either step up or step down). Each topology is designed for specific voltage conversion requirements. Switching regulators are widely used in electronic devices ranging from mobile phones and laptops to industrial power supplies and automotive systems due to their energy efficiency and compact size.
