Keitikliai

Keitikliai, meaning converters or inverters in Lithuanian, are electronic devices that change the form of electrical energy. Primarily, they are known for converting direct current (DC) to alternating current (AC), a function essential for powering many household appliances from DC sources like batteries or solar panels.

These devices work by using semiconductor switches to rapidly turn on and off the DC input, creating a series of pulses that mimic an AC waveform. More sophisticated keitikliai employ techniques to smooth these pulses into a more sinusoidal output, ensuring compatibility with sensitive electronic equipment. The frequency and voltage of the output AC can often be controlled.

Beyond DC to AC conversion, keitikliai can also perform other functions, such as AC to DC conversion (rectification), changing the voltage level (e.g., step-up or step-down converters), or altering the frequency of AC power. They are crucial components in a wide range of applications, from uninterruptible power supplies (UPS) and renewable energy systems to electric vehicles and industrial motor control. The efficiency and waveform quality of a keitiklis are key parameters determining its suitability for a particular task.
