This paper reports the development of a low-power switchedcurrent algorithmic A/D converter based on a new algorithm, providing the bit conversion in three-cycles. The converter uses modified SI type current copiers to reduce the overall area and power consumption. The analog portion of the converter occupies only 0.35mm area in 3μm CMOS technology. The simulation results show that the converte...

Since the second half of the 20th century, various devices have been developed in order to reduce the emissions of harmful substances at the exhaust pipe of combustion engines. In the automotive field, the most diffuse and best known device of this kind is the “three way” catalytic converter for engines using the Otto cycle designed to abate the emissions of carbon monoxide, nitrogen oxides and...

This project proposes a novel three phase nine switch AC/AC converter topology. This converter features sinusoidal inputs and outputs, unity power factor, and more importantly, low manufacturing cost. The Operating principle of the Converter is elaborated, its modulation schemes are also discussed, and experimental results from a 5kVA prototype system are provided.

People usually research modulation mode 3 of SVM for matrix converter discussed in this paper. Actually, other different modulation modes of SVM for matrix converter are worth studying. Two novel modulation modes are put forward for matrix converter for the first time in this paper, expanding its modulation modes of SVM. First, SVM for matrix converter is described. Then the 3 modulation modes ...

The Matrix converter is a forced commutated Cyclo-converter with an array of controlled semi conductor switches that connects directly the three phase source to the three phase load. The matrix converter is a direct AC-AC Converter. It has no limit on output frequency due to the fact that it uses semiconductor switches with controlled turn-off capability. The simultaneous commutation of control...
