Electiical drives aie composed of rotating electric machines (which transform electric energy into mechanical energy or viceversa), power electronic converters and controllers connected together in order to operate the whole electrical drive in steady state or vaiiable speed working operations. 

Variable speed drives are generally based on a set of an electric machine driven by power electronic converters and controls, which are implemented in electronic cards. The whole system makes possible the speed regulation of the electric machine.

In power generation plants, e.g. in wind turbines, electronic converters and inverters are used. Faults in these components can degrade the performance of power distribution systems and lead to failures. In [19, 22], it is reported that semiconductors and electrolytic capacitors in power power electronic converter systems have a higher failure rate than other components.

In this section, design considerations for a 1-kW fuel cell powered line-interactive UPS system with one hour of backup power employing modular (fuel cell and power converter) blocks is discussed. Figure 8-13 shows two commercially available PEFC fhel cells (25 to 39V, 500W) [1] along with suitable DC-DC and DC-AC power electronic converter modules. Commercially available supercapacitors [5] supply transient power at the output terminals. Two possible power-conditioning architectures are investigated. 

Active filter A form of power electronic converter designed to effectively cancel harmonic currents by injecting currents that are equal and opposite to, or 180" out of phase with, the target harmonics. Active filters allow the output current to be controlled and provide stable operation against AC source impedance variations without interfering with the system impedance.
