RESEARCH AND COMPARISON OF EXISTING CIRCUIT-TECHNICAL SOLUTIONS FOR LED POWER SOURCES

The aim of the work is to research the existing concepts and circuit solutions for LED drivers. Circuit solutions are tested by functional tests. So the scheme ofnew passive correctors, methods for stabilizing the LED current, etc. are tested to achieve the desired functional characteristics under various conditions of the driver. The working conditions, for example, are variable input mains voltage, ambient temperature, idle speed, short circuit condition, output load, dynamic processes, etc. Each circuit solution has its own target functional parameters, which will be paid attention to in tests. The main target displays of the current stabilization scheme are stabilization accuracy and efficiency.
