Abstract This paper aims to improve efficiency in interior permanent magnet synchronous motor(IPMSM) drives for electric vehicles. The controllable electrical loss which consists of the copper loss and the iron loss can be minimized by the optimal control of the armature current vector. The control algorithm of current vector minimizing the electrical loss is proposed and the optimal current ve...

The electric current is omnipresent and indispensable in our life. But there are always threatening dangers connected with it. One of them is the electric short circuit and we have to protect people and facilities from its effects. This protection is often provided by power circuit breakers or motor protective circuit breakers. These devices are able to detect the short circuit, limit the curre...

In this paper, Plug-in Fuel Cell Electric Vehicle (PFCEV) is considered with dual power sources including Fuel Cell (FC) and battery Energy Storage. In order to respond to a transient power demand, usually supercapacitor energy storage device is combined with fuel cell to create a hybrid system with high energy density of fuel cell and the high power density of battery. In order to simulate the...
