Aspiring Power Electronics Engineers Must Master Four Aspects Of Converter Design

Focus:

Power converters are not trivial to design. They involve analog and digital circuits; discrete-time, sampled feedback loops; parasitic elements in components that significantly affect circuit behavior; and control models of the nonlinear element (the PWM switch) that have taken decades to refine. In all, power electronics is one of the most demanding areas of electronics. This article presents a brief overview of power converter design, describing four essential aspects of this activity—circuit waveforms, magnetics, parasitic resonance, and control—and highlighting some of the complexities of converter design. This article will also point out some of the skills engineers need to overcome converter design challenges.
