Tips: Switching power supply characteristics and applications
SMPS Main characteristics:
- Small size and weight: the size and weight of switching power supply proves to be 20-30% of linear power, because it has no industrial frequency transformer.
- Low energy consumption and high efficiency: power transistor operates in switch state, so it presents lower energy consumption and higher conversion efficiency with a conversion rate of 60-70%. As a contrast, linear power supply only presents a conversion rate of 30-40%.
Switching power supply is widely applied to industrial automatic control, military equipment, R&D equipment, LED lighting equipment, industrial control equipment, communication equipment, power equipment, meters, medical equipment, semi-conductor refrigeration and heating equipment, air purifiers, electronic refrigerators, LCDs, audio-visual products, security and monitoring devices, LED strip lights, computer cases, digital products and various instruments.
