Figure B.4 shows the load formed by the three single-phase rectifier and the switches that allow selecting energy storage elements at the dc side of each rectifier. Of 55 mH and a capacitor of 2200 mF at the dc side of each rectifier. Similarly as in the previous configuration was assembled in a box that enables easy setup with an inductance It is a single-phase bridge rectifier which supports a maximum current at the dc side of 25 A and a repetitive peak maximum voltage of 1000 V. The second configuration is based on the GBPC2510 rectifier module from International Rectifier. An external variable resistor completes the load.

For quick load setup, the rectifier module is P. The maximum permissible current at the dc side of this device is 35 A and the maximum voltage repetitive peak is 600 V.
A three-phase rectifier configuration is composed by a 36MT60 module from International Rectifier. The first load at the dc side is connected a high inductance in series with a resistor and the second load a capacitor in parallel with a resistor are connected at its dc side. They are based on a noncontrolled three-phase rectifier. Two types of nonlinear three-phase loads have been used for different essays. These elements allow us to consider the effect of grid impedance on the laboratory prototype. In series with the voltage source is connected an inductance of 2.34 mH with a resistance of 1.3 Ω. It has an RS-232 connection that together with the CGUI32 software allows programming (Figure B.2) through a PC.
This source allows programming of the voltage signals required for testing Electromagnetic compatibility according to IEC 61000. It is a programmable three-phase source, which can supply from 4.5 kVA to 10 A in a voltage range from 0 V to 150 V and upto 5 A when the range is selected as 0–300 V. Model 4500-iL from California Instruments has been used as a power supply. Hereinafter, the main characteristics of the devices used in the prototypes designed for this purpose are presented. Figure B.1 shows the general scheme of the laboratory prototype. Therefore, the description of both prototypes will be made jointly because they share the majority of developments. Also, in both topologies the same control strategies are applied. The only difference is due to the parallel connection of a passive filter in the case of the hybrid filter. In both prototypes the power circuit is very similar.
Both platforms share many designs of the individual components and the following exposition will take advantage of these similarities.ī.1 Experimental Platform for Series and Hybrid APF Tests In Chapter 5 an experimental prototype of series filter is developed and in Chapter 6 a hybrid filter is constructed. The second one is a general purpose platform that has been selected for the shunt and series-shunt APF cases of Chapters 4 and 7, and is also used for another active power filters configurations and developments of the laboratory. The first of these has been used for the development of the series and hybrid examples of Chapters 5 and 6, which has a specific design for these applications. Two different platforms have been considered to apply for the various practical cases. Experimental Implementations This appendix describes the laboratory setups used to obtain the experimental cases included in this book.
