TOPSwitch-GX单片开关电源的设计

Design of Single-Chip Switching Power Supply Based on TOPSwitch-GX

电源性能的优劣直接影响电器产品的质量,传统采用的工频变压器由于体积大、耗材多、损耗大、效率低正逐步被淘汰。针对上述的这些缺点,利用TOPSwitch-GX芯片,提出一种单片开关电源的设计。与传统的工频变压器相比,它具有更加优越的性能。

The performance of power supply will directly affect the quality of electric products. The traditional power frequency transformer will be eliminated for its large volume, excessive materials, great loss and low efficiency. According to the above disadvantages, a design of single-chip switching power supply is pro- posed by TOPSwiteh-GX chip. It has better performance than that of traditional power frequency transformer.
