摘要： An inverter apparatus, and a light-emitting device and an image display device using the same are provided to operate a plurality of loads by sharing a control circuit for performing feedback control of on/off status of transistors of a switch circuit. An inverter apparatus comprises the following parts: a transformer including a first winding and a second winding; a switching circuit including a plurality of transistors connected to the first winding of the transformer, for applying a locked voltage which is less than a locked voltage and the input voltage to the first winding of the transformer; a plurality of capacitors in which one stage is connected to a second winding of the transformer and the other stage is connected to a plurality of loads; and a control circuit(20) for performing feedback control of on/off status of the plurality of transistors of the switch circuit and adjusting supply of switching power of the first winding of the transformer.
