BMP is located on the last stage of various electronic devices as a type of converter. It requires small size, light weight, and standardization that supplies electricity to parts within each board. This is a variance connection method that supplies power by variance per voltage in the concentrated connection method that supplies power by packing various voltages such as converters. For converters, the current trend is to convert to BMP. This field is receiving a great deal of attention due to the desirability of small size and light weight power. This is a power device that can be applied in any sectors that require small size and light weight, but it can be configured with most technologies of other power devices and supplies stable power.
