POWER SUPPLY COMPRISING MULTIPLE OUTPUTS

摘要

The present application relates to a power factor correction stage, and more particularly, to a switch mode power supply comprising the liquid crystal display device. Thepower factor correction stage comprises a rectifying circuit connectable to an alternating current energysupply. The power factor correction stage comprises a transformer circuit configured to galvanically insulate the alternating current energy 5 supply from atleast one load. The transformer circuit comprises at least one power factor correcting inductor. The transformer circuit comprises at least one primary inductor formed by a first inductor. The transformer circuit comprises a first secondary inductor coupled to the primary inductor via a core. The transformer circuit comprises at least a second secondaryinductor coupled to the primary inductor via the core, wherein 10 the secondaryinductors are formed such that at least one output voltage of the transformer circuit is adjusted according to requirements of the at least one load.
