摘要： A parallel resonant converter is operated directly from rectified mains. The single-stage power supply copes with present dimmers (such as leading edge dimmers and trailing edge dimmers) and meets EMC standards. The operating scheme allows avoiding exciting 100/120 Hz flicker without using an electrolytic capacitor. This is possible during both full operation and dimmed operation. Deep dimming down to less than 5% is possible and does not require extra power components.

摘要翻译： 并联谐振变换器直接由整流电源运行。 单级电源适用于目前的调光器（如前沿调光器和后缘调光器），符合EMC标准。 操作方案允许避免在不使用电解电容器的情况下激发100/120 Hz的闪烁。 这在完全操作和调暗操作期间都是可能的。 深度调光可能低于5％，不需要额外的功率部件。
