6. Conclusion

The chapter delves into the design and implementation of high-voltage switched-capacitor converters (SCCs) for low-power applications. It begins by discussing the fundamental concepts of SCCs, including their operational principles, loss mechanisms, and control strategies. The core contribution is a fully integrated DC-DC converter operating at 400 V DC, which overcomes challenges such as diminished component quality and increased parasitic losses. This converter achieves a significant boost in power density and efficiency, setting new benchmarks in its class. The chapter further broadens the input voltage range to 31 V–325 V DC, facilitating applications with variable DC input requirements. It also introduces an innovative AC-DC converter topology that reliably pre-charges the SCC and incorporates an optimized linear regulator, significantly reducing the buffer capacitance and enhancing power density. These advancements pave the way for more cost-effective, reliable, and compact power conversion solutions in various industries.
