In this paper, the operation principle of the electronic transformer and the factor influenced the switching frequency of electronic transformer are introduced in detail.Meanwhile a regulated power supply which is reformed by electronic transformer is proposed.Using voltage and current feedback, it realizes the constant output voltage and the over-current protection.The feedback theory is given in detail.The 150 W regulated power supply with the advantages of simple structure, light weight and low cost is developed.
