This paper studies simple hyperchaotic circuits consisting of one linear 3-port voltage-controlled current source (ab. VCCS), two linear capacitors and one dependent switched capacitor. The dynamics is described by a normal form equation and a return map can be derived. Using a mapping procedure, it is shown that the circuits exhibit interesting hyperchaotic attractors.

A dual two-level inverter fed open-end winding induction motor drive with a single DCpower supply is proposed. The proposed scheme produces voltage space vector locations identical to those of a conventional three-level inverter. In the conventional neutral-clamped three-level inverter, the series-connected DC link capacitors carry the load current, resulting in a fluctuating neutral point. Als...

In this paper we compare characteristics of different FIFO packet switch types. In accordance with our expectations, the best results are obtained by using the output-queued packet switches. The main drawback of these switches is the need for a fast switching fabric. This can be avoided by using the input-queued packet switches, whose performance depends upon individual packet sizes. Characteri...

In this paper we review relevant problems in the modelling of DC-DC converters with switched capacitors. We study several approaches that overcome the exposed modelling difficulties, addressing ideal and nonideal cases and using dynamic equations that are valid in a large signal domain.

An alternative method for characterizing capacitor matching is presented. The basic idea of this method is to sense the mismatch among the capacitors by amplifying the error voltage using an iterative switched-capacitor scheme. Through simulation, this method has shown attractive property for sensing capacitor mismatches down to 1% and smaller.

With the ongoing expansion and growth of electric power industry, the use of power flow controllers is becoming more prevalent in modern power systems. The needs for system enhancement trigger the advancement of FACTS technology which offers superior features in increasing system stability and performance. Devices like TCSC can reduce line reactance significantly and thus enhance the maximum po...

This paper presents work towards heterogeneous integration of high-efficiency power amplifiers (PAs) with tuner and biasing circuits implemented with micro-electro-machined elements. The PAs operate in switched mode with over 70% efficiency at X-band. Many such switched-mode amplifiers are used as the active portion of spatial power combining antenna arrays, with 2.3kW ERP at 8.4GHz at 65% drai...

Abstract: Analog sampling systems based on switched capacitor techniques offer performance superior to that of flash A/D converters with respect to cost, density, dynamic range, sampling speed, and power consumption. This paper proposes a 500 MHz switched capacitor analog waveform sampling circuit for the camera electronics of the Cherenkov telescope. An experimental 4 channel analog memory wit...

The proposed zero-current switching switched-capacitor (ZCS SC) DC-DC converter is an innovative bi-directional power flow control conversion scheme. A zero-current switching switched-capacitor stepup/step-down bi-directional converter is presented that can improve the current stress problem during bi-directional power flow control processing. It can provide a high voltage conversion ratio of n...
