Jõudluselektroonika

Jõudluselektroonika, also known as power electronics, is a branch of electrical engineering that deals with the application of solid-state electronics for the control and conversion of electric power. It involves the study and design of electronic circuits and systems that can efficiently process and manage electrical energy. These systems are crucial for a wide range of modern technologies, enabling efficient power delivery and control in various applications.

The core components of power electronic systems are power semiconductor devices such as diodes, transistors (like MOSFETs and IGBTs), and thyristors. These devices act as electronic switches, rapidly turning electrical current on and off to modify voltage and current characteristics. By arranging these components in specific configurations, power electronic converters can perform functions like AC to DC conversion (rectification), DC to AC conversion (inversion), DC to DC conversion (chopping), and AC to AC conversion.

Key objectives in the design of power electronic systems include high efficiency, minimal power loss, good power quality, reliability, and compact size. These systems are fundamental to energy-efficient technologies, including variable speed drives for motors, renewable energy integration (solar and wind power converters), electric vehicle charging infrastructure, uninterruptible power supplies (UPS), and high-voltage direct current (HVDC) transmission. The continuous advancement in semiconductor technology and control strategies is driving further innovation and efficiency improvements in the field of jõudluselektroonika.
