Switchmode Power Supplies

Our guiding principle is to provide both standard and custom switchmode power supplies to suit a variety of applications. In addition to our wall and rack power supplies, Dynapower offers the latest generation of air and water-cooled switchmode DC power supplies, featuring an innovative design that provides users with an operational and installation advantage.

The switchmode DC power supply is a solid state AC to DC power conversion system. The system functions by first rectifying the AC input to an unregulated DC voltage. This intermediate DC voltage is then chopped using pulse-width modulation through an H-Bridge configuration into a high-frequency transformer. The output of the transformer is rectified and filtered to provide a precisely controlled high current DC output with <2% AC Vrms content. The high switching frequency enables a smaller package, less ripple, higher efficiency and provides for a faster control loop.

Benefits of Switchmode Power Supplies include:

  • Lower cost of operation (than traditional SCR Units)
  • Compact design (wall, rack & modular configurations)
  • Inherent low ripple
  • Higher efficiency
  • Higher power factor
  • Local and remote automation capabilities
  • CSA CE and third party design and label models available
