The implementation of power switching converters by low cost embedded systems is in general limited by the low operating frequency as well as the resolution of the variable duty cycle waveform which controls the power converter. The paper analyzes how the use of dedicated hardware units may partially overcome these limits and whether a microcontroller in an embedded system may both operate as a power supply controller and at the same time perform other application tasks which do require a limited amount of processing power.
