Working Principles

The ICE1CS02GXUMA2 is a power factor correction controller designed to improve the efficiency of power supplies. It operates by regulating the input current waveform to achieve a near-unity power factor. By actively controlling the input current, it reduces harmonic distortion and improves energy efficiency.

The device utilizes a boost converter topology to achieve power factor correction. It adjusts the duty cycle of the switching transistor based on feedback from the output voltage and current sense inputs. This control mechanism ensures that the input current follows the shape of the input voltage, resulting in a power factor close to 1.
