Challenge

Commercial switch-mode power supplies must comply with a number of industry safety standards such as electric current harmonics, thermal and electrical protections and electromagnetic interference (EMI). The challenge is to design a power system that meets all these safety requirements while remaining cost-effective.

 

Solution

The UTS Tech Lab team developed an interactive testing platform to assess key safety standards and allow for optimisation of switching power supply development and design.
