摘要：<p>A multi-voltage power supply includes a transformer (T), a first output circuit (120) to generate a first output voltage using a voltage transferred to a secondary winding (L3) of the transformer (T), and a first output voltage controller (130) to control a voltage supplied to the primary winding (L1) of the transformer (T) according to the first output voltage. The multi-voltage power supply includes second through Nth output circuits (140) to generate second through Nth output voltages using the voltage transferred to the secondary winding (L3) of the transformer (T), and second through Nth output voltage controllers (160) performing control in order to linearly output the second through Nth output voltages by feeding back the second through Nth output voltages. Accordingly, multiple (at least two) output circuits, which are on the secondary winding (L3) side of the transformer (T), to realize multiple output voltages can be independently controlled, and in particular, by linearly controlling the multiple output circuits, the multiple output voltages can be stably controlled regardless of the number of output voltages.</p>
