Plug-in hybrid electric vehicles (PHEVs) are equipped with a high energy density battery pack, which should be externally charged form the grid. This requires a high power battery charger circuit which can operate at universal input voltage and be capable of maintaining the required output voltage and current with low ripple. The topology composed of PWM boost rectifier cascaded with a bidirectional...
This paper addresses the timely issues of power loss calculation methods in the most common voltage source three phase PWM converters (VSC). There are mainly two kinds of power semiconductor losses to be considered, the conduction losses and the switching losses. A reconfigurable Induction Motor (IM) drive is controlled by the conventional PWM and space vector PWM based methods. The power losses will...
Electric motors are an integral part of industrial plants with no less than 5 billon motors built worldwide every year. Residential and commercial appliances such as refrigerators and air conditioning systems have been using conventional motor drive technology. The machines in these applications typically have low efficiencies and high maintenance. Brushless DC (BLDC) drives are known for higher efficiency,...
Various phenomena can deteriorate the performance of induction motors and cause potential safety hazards. This can be harmful for the respective applications. Deficiencies like unbalanced voltages due to an unbalance in the power grid or harmonics in the voltage source could result in problems like excessive losses, over-voltages, mechanical oscillations, and interference with control electronics...
