Abstract In this paper, a low power switching power supply is introduced for intelligent electrical apparatus. The article describes the architecture selection, working principle, circuit and transformer design and the design consideration of reliability. A board was designed based on that topology. Its cost and size is low. The results show that the power supply meets the design requirements, has good electromagnetic compatibility and high application value.
