This paper shows a novel design and implementation of a multi-purpose power module used to manage the energy produced by renewable energy sources and at the same time compensate the discontinuous power absorption from loads, with the final goals to increase power distribution efficiency and grid stability.
Solar photovoltaic (PV) systems have been an area of active research for the last few decades to improve the efficiency of solar PV module. The non-linear nature of IV curve of solar PV module demands some technique to track the maximum voltage and maximum current point on IV curve corresponding to Maximum Power Point(MPP). Thus, Maximum Power Point Tracking (MPPT) techniques are widely deployed for...
In automotive systems, piezoelectric injectors allow fine electronic control over the fuel injection time and quantity. They are typically driven by current controlled bidirectional converter. This power board is managed by an ASIC device which is part of the car ECU. This paper describes a new FPGA-based ASIC fast prototyping methodology for piezo injectors control units.
In automotive applications piezoelectric actuators (used as injectors) typically require more than 150 V in order to be driven in a smaller time with respect to magnetic actuators, allowing for example more precise injections in the same motor cycle. This is a big concern in automotive environment, where the 12 V battery voltage is still the main power source available. In this paper an efficient...
A power driver has been developed to control piezoelectric stack actuators used in automotive application. An FEM model of the actuator has been implemented starting from experimental characterization of the stack and mechanical and piezoelectric parameters. Experimental results are reported to show a correct piezoelectric actuator driving method and the possibility to obtain a sensorless positioning...
