Design of Switching Power Supply Circuit System in Frequency Conversion Appliance Driver
description:
This paper introduces the design of frequency conversion appliance driver using intelligent power device IPM, and proposes a switching power supply design scheme based on TOPSwitch according to the IPM drive power requirement. The test results show that the power supply scheme has good dynamic and static characteristics and can meet the requirements of reliable operation of the frequency conversion appliance driver.
The attachment is a design schematic. See the PDF document for details!
SMA means surface mount assembly. It is a new generation of electronic assembly technology, which compresses traditional electronic components into a device with a volume of only a few tenths.
Surface mounting is not a new concept, it is derived from earlier processes, such as flat mounting and mixed mounting.
For the assembly of electronic circuits, a point-to-point wiring method was initially adopted, and there was no substrate at all. The packaging of the first semiconductor device uses radial pins, which are inserted into the through holes of the monolithic circuit boards that have been used for the packaging of resistors and capacitors. Active components have been widely used in the past ten years.
