SINAMICS DC Master is the scalable DC drive system for simple and demanding applications, flexibly expandable from standard to the high performance solution. Many years of experience concentrated know-how and consistent development guarantee highly reliable state-of-the-art solutions. With the two diffe...
The motor type that is coming to the fore is the Brushless DC type (BLDC), basically a reversed-brushed DC motor, allowing the brushes to be removed. These offer better performance, improved efficiency and long life. The downside is that a multiphase AC supply must be pr...

square waves of high frequency, usually 25kHz or above, to make the noise from the fan above the audible human range. The PWM signal can start or stop the motor, depending on the high and low state of it. When the PWM signal is high, the motor runs, otherwise, ...
A good agreement between the numerical solutions and experimental results was achieved. Since the power supplied to the DC motor was relatively high, angular speed of the DC motor was almost constant for constant input voltage and sufficiently good results were obtained by mathematical modelling ...

The optimum value of TSR depends on the type and aerodynamics of the turbine. Figure 2 shows the Cpvs. TSR curve. Figure 2. Cp vs. tip speed ratio (TSR) curve. The transfer function of the PMSG motor 𝐺𝑝𝑚𝑠𝑔Gpmsg(s) is given as 𝐺𝑝𝑚𝑠𝑔(𝑠)=𝐹𝑒𝑞...
It is assumed capacitors C 1 , C 2 , C 3 , C 4 and C 5 are equal. 3.2. 1st Modified-Triple-Level Boost Converter (1st M-TBC) One of the solutions to obtain a high voltage gain converter is presented by implementing a voltage-lift switched inductor structure that replaces the ...
As an emerging technology, on-board HESDs are usually composed of different types of energy storage devices, namely, batteries (BATs), supercapacitors (SCs), and flywheels, where the hybridization solutions to BATs and SCs are widely applied in electric vehicles and rail transportation [5,6]. ...
