In this paper we propose a controlled cross-coupled switched-capacitor based embedded DC-DC buck converter based on non-overlapping rotational time interleaving switching scheme and frequency control regulation. Proposed converter uses low swing internal signals to control half of the switches. In addition to reduction of switching power loss, the low swing control signals help to use smaller switches...
An architecture of inductor-less DC-DC boost converter for high efficiency and low output ripple is proposed. Output ripple is reduced by splitting flying capacitors into a number of smaller elements and using a new switching scheme called non-overlapped rotational-interleaving (NORI). The proposed switching scheme also helps to eliminate reversion and shoot through current hence improves the power...
This paper deals with the efficiency improvement of an embedded hybrid DC-DC converter which is suitable for high dropout embedded regulation. In the proposed topology, power efficiency is improved by eliminating shoot-through current of switched-Capacitor module using Non-overlapped Rotational Time Interleaving (NRTI) switching scheme. In addition to the improvement in power efficiency, this scheme...
Here we propose a low voltage low ripple hybrid dc-dc converter. In the proposed topology, along with a linear regulator a switching capacitor is used to store and recycle the charge for better power efficiency. Linear regulator is used to reduce the amount of output voltage ripple that comes from the switching capacitor. The output noise is further reduced by introducing a synthesized counter noise...
