A large IT Peripherals company required a high wattage switch mode power supply as part of its new printer program. The power supply has geometric constraints to fit into dense packing of printer enclosure and to meet the requirements of CE marking for safety.

The SMPS was designed and developed ground up which includes hardware design, component choice and sourcing, PCB design and development, Boards integration, pre qualification tests to meet CE requirements. The product was tested for all functional test specification defined by the printer manufacturer.

Project Highlights

• Design and numerical modeling of the SMPS
  
• The design was a Flyback SMPS with Integrated PWM Switcher ,Front-end surge suppressor and transient noise suppression
  
• Functional Prototype was developed based on the new design
  
• Functional testing with the printer
  
• Safety / EMC testing
  

Result :

The SMPS is fully integrated with the printer and the printers are well received in the market for small and medium business applications
