this paper presents the new topology of three phase on line uninterruptible power supply (ups) by employing t-source inverter (tsi) with maximum constant boost pulse width modulation (pwm) control and the results are compared with the conventional uninterruptible power supply (ups). the conventional ups consists of voltage source inverter (vsi) with step up transformer or dc-dc booster which de...

LCL and LCTL frequency characteristics for the balanced pair cable of power line communication system were measured for the several grounding conditions such as no, input side and output side groundings. In consequence, it is clear that the input side grounding for LCL became the worst, but the output side grounding for LCTL became the worst, and the tendency of the LCTL frequency characteristi...

The article describes a way of evaluating the power line channel frequency response and input impedance by means of the linear time-invariant (LTI) power line generator. Two possible methods are introduced for the calculation of primary parameters: the first method depends on the physical realization and physical dimension of the cable, and the second method is derived from the data provided by...

This paper presents the design of a power line communication model. Primarily, it is focused on a realization of a communication model with a power line channel. The model is composed of a PLC communication model, a model of power lines and a noise model. Power lines are modelled through a chain parameter describing the relation between the input and output voltage and current of the two-port n...

A complete system able to measure complex impedance, both in magnitude and phase, of an automotive electrical load is designed. The development of such system emerged from the need of measure the impedance of these loads in a wide range of frequencies (100 kHz to 30 MHz) while being connected to power supply and in operation. This powered up condition introduces several problems when the impeda...
