  • Publication number: 20240105436
    Abstract: The performance of a power supply module is to be improved. The occurrence of discharge in the power supply module is to be prevented, and the size of the power supply module is to be reduced. In a power supply module, substrates are provided being stacked in a planar view. A low voltage circuit and a high voltage circuit are formed on a first substrate such that a distance is kept for preventing surface discharge, and a low voltage circuit is formed on a second substrate. A distance between a component of a high voltage alternating current circuit on the high voltage circuit and a component of the low voltage circuit is three times a shortest distance, at which space discharge does not occurs, between a component that constitutes a high voltage direct current circuit on the high voltage circuit and a component that constitutes the low voltage circuit.
