Design of driving power supply for double cold source dehumidifier

Abstract： At present, multi-functional power supply is widely used in all kinds of drive control products. The traditional drive control power is mostly single input and single output, which is difficult to meet the needs of a variety of power supply port control equipment. Moreover, there is serious electromagnetic interference in some complex experimental environment and products with require high EMI requirements, which improves the design cost potential. To solve the above problems, a low-cost, high reliability, compatible with AC 220 V or DC 310 V dual-mode input, multi-channel output and high integration switching power is developed. Field experiments show that the four power output is accurate. The error is less than 1% and electromagnetic interference is easy to pass. The power can meet the needs of most motherboard power supply equipment, and has been applied to driving control power supply for double cold source dehumidifier.
