ELECTROMAGNETIC COMPATIBILITY： 7.1 Electromagnetic Interference (EMS)： FCC Part 15, subjecting, class B ； CISPR-22, class B 7.2 Electrostatic Discharge (ESD)：Comply with IEC801-2. 7.3 Radiated Susceptibility (RS)：Comply with IEC801-2. 7.4 Power Factor (Harmonics)：Comply with IEC1000-3-2, IEC1000-3-3 『Active Power Factor Correction』 Active Power Factor Correction (the advance technology most used in high power SMPS) used a per-regulator before the main PWM convert circuit, the current feedback technology. Regulated current drawing flow AC sinusoidal wave. Therefore, the THD less than 5%, and 3 the power factor increase to applied 0.99 or higher. This method of PFC knows as Active Power Factor Correction because applied active components and circuit inside. It can provide high power factor (up to 0.97 ~ 1), can operate in world wide input range (100V ~ 240VAC). An intelligent solution for high regulation, high power density power designs 8.
