Abstract
This chapter presents an offline chip-scale power supply to solve the design challenges at high AC input voltages, as identified in Chap. 2. State-of-the-art approaches for the different stages of an AC–DC converter are discussed, and the structure of the implemented AC–DC converter is developed. It includes a detailed analysis of the developed active-zero-crossing buffer that enables the on-chip integration of the buffer capacitor up to several milliwatts of output power. This chapter also presents the required control circuits, the loss breakdown, and the experimental results of the implemented AC–DC converter. A comparison of the converter to prior art publications and commercially available power modules concludes this chapter.
