PROBLEM TO BE SOLVED: To provide an insulating power supply device capable of achieving downsizing of a configuration for supplying a driving voltage to the switching S¥# and an excitation coil of resolver, and also capable of achieving the low cost.SOLUTION: Primary side coils 80a, 82a, 84a, 86a, 88a constituting the respective first to fifth transformers 80, 82, 84, 86, 88 are connected in parallel to each other. Then, a part of the voltage supply objects corresponding to the respective first to fifth transformers 80, 82, 84, 86, 88 is the switching element S¥# and the residue of the voltage supply objects is an excitation coil of resolver. |
