Filtering Made EasyPicor QuietPower®

DC-DC Filters: Input EMI Filters and Output Ripple Attenuators

DC-DC Filters

Vicor's QPx series of active EMI/EMC filters providing high levels of attenuation in a fraction of the size of traditional solutions.

The Picor QuietPower QPO output ripple attenuator uses proprietary active filtering to reduce power supply output ripple and noise (PARD) over 30 dB from 1 kHz to 500 kHz.

The Picor QuietPower QPI active EMI filter works in conjunction with a specific set of Vicor converters to deliver optimal efficiency, power and protection.

Picor QuietPower® EMI Input Filter Modules

  • Provides conducted common-mode (CM) and differential-mode (DM) attenuation from 150kHz to 30MHz (CISPR22 range)
  • Optimized for applications that require EN55022 Class B limits
  • 12V, 24V, & 48V nominal input voltages
  • High density open frame and lidded surface mount LGA packaging
  • Saves up to 50% board space vs. standard filters
  • Compatible with most industry standard DC-DC converters
 

Picor QuietPower® Output Ripple Attenuator Modules

  • Reduces power supply output ripple to less than 10mVp-p
  • Greater than 30dB PARD attenuation from1kHz to 500kHz
  • Greater than 99% efficient
  • Improves transient response of DC-DC converters
  • Can reduce required output capacitance by a factor of 10
  • User selectable optimization of attenuation, power dissipation, and transient performance
  • High density open frame and added surface mount LGA packaging
  • Compatible with most industry standard DC-DC converters
