Power factor correction solution meets new EMC directive

9 May 2001 Power Electronics / Power Management

Intersil claims to have developed a simple and efficient solution to meet the recently-approved European standards for boost power factor correction (PFC) of power supply standards at low cost. Intersil has combined its SMPS IGBT with its recently announced Stealth Diodes resulting in a low cost, efficient and high power-density design to meet the latest EMC testing requirements.

The EMC standard applies to all electrical and electronic equipment including computers and telecoms equipment with input currents up to 16 A for connection to public, low-voltage distribution systems such as commercial and household electrical outlets and specifies limits for harmonic current emissions and EMI. Intersil says that for optimum PFC design, designers can choose matched IGBT and Stealth Diode combinations as per the table below.
