| Abstract: | To introduce the active power factor circuit into PWM power supply circuit can lead to a power factor higher than(0.99) and decrease the input current distortion to less than 5%,which greatly diminishes the pollution to the electrical grid.IR1150 is a specially designed APFC control IC,of which working principle is based on one-cycle control(OCC).The simplicity of control circuit adopted IR1150 facilitates the design and test,reduces the volume and lowers the cost.The function and inner circuit of IR1150 is discussed in this paper.A 400W experimental circuit is built and the experimental results verified the OCC methed. |
