Energy storage inductor zero crossing

Why is inductor-based DC–DC converter used in energy harvesting applications?

As explained in Chap. 3, an inductor-based DC–DC converter is widely used in energy harvesting applications due to its high efficiency [67, 76]. The efficiency of the converter depends on the inductor quality factor, the technology used, losses in the converter and the control circuit.

Does a coupled inductor cause zero-crossing distortion?

However, a coupled inductor will also worsen the zero-crossing distortion process. This paper first introduces the working principle of the interleaved totem-pole PFC converter with a coupled inductor based on a detailed analysis of modes, and then analyzes the influence on the zero-crossing process caused by the coupled inductor.

What are ZCS control techniques for inductor-based Boost converters?

Part of the book series: Analog Circuits and Signal Processing ( (ACSP)) In this chapter, ZCS control techniques for inductor-based boost converters are presented. The ZCS circuit controls the high side switch of the synchronous inductor converter to maintain the output voltage and hence the efficiency.

How can a zero-crossing point model be used to predict inductor current?

By establishing a model for predicting the zero-crossing points of the inductor current, the current at the beginning and end of each stage can be accurately estimated. In comparison to traditional methods, the proposed approach eliminates the need for ZCD auxiliary circuits and current sensors.

How does a zero-crossing converter work?

The zero-crossing prediction is achieved solely by sampling the input and output voltages, resulting in a simplified hardware circuit design. Furthermore, the extended conduction time of the SR enables the realization of full-range ZVS, enhancing the converter’s flexibility in complex operating conditions.

What is ZCS in a synchronous inductor converter?

The ZCS circuit controls the high side switch of the synchronous inductor converter to maintain the output voltage and hence the efficiency. In the first section, several reported ZCS techniques are explained and compared in regard to design, complexity, and efficiency.
