Title:
LED LIGHTING DRIVER POWER SUPPLY SYSTEM FOR HIGH-VOLTAGE ALTERNATING CURRENT SYSTEM
Document Type and Number:
WIPO Patent Application WO/2017/088223
Kind Code:
A1
Abstract:
An LED lighting driver power supply system for a high-voltage alternating current system, comprising a three-phase alternating current system, a multi-pulse transformer rectifier, and a non-isolated DC/DC converter circuit. The three-phase alternating current system and the non-isolated DC/DC converter circuit are connected respectively to an input end and an output end of the multi-pulse transformer rectifier. The multi-pulse transformer rectifier comprises an alternating current-side three-phase filter inductance (Ldm), a multi-pulse transformer (T1), several three-phase rectifier bridges (B1, B2, and B3) corresponding to the number of pulses of the multi-pulse transformer, a direct current-side filter inductance (Ldc), and a direct current capacitor (Cdc). The alternating current-side three-phase filter inductance is connected to an input end of the multi-pulse transformer. Alternating current input ends of the three-phase rectifier bridges are connected to an output end of the multi-pulse transformer. Direct current output ends of the three-phase rectifier bridges are directly connected in parallel and connected to the direct current-side filter inductance and the direct current capacitor. The LED lighting driver power supply system employs a multi-pulse transformer rectifier technique, has high reliability, high efficiency, high power factor, and low harmonics content, and is inexpensive.
