Study of the harmonic content of the current consumption led-driver using programming voltages GW INSTEK APS-71102

LED-driver experimental harmonic current emission research considered in accordance with the requirements of IEC EN 61000-3-2 “Electromagnetic compatibility (EMC) -Part 3-2: Limits - Limits for harmonic current emissions (equipment input current ≤ 16 A per phase)”. The main sources of higher harmonics appearance and the methods of their removing are analyses. The main technical characteristics and the main features of programmable power supply GW INSTEK APS-71102 are considered. Research of the LED-driver ITSK-17507 shows full compliance of harmonic current emission with the requirements of IEC EN 61000-3-2.
