"Active Power Factor Control - Requirements and Techniques" and "Analysis of Input Current Harmonics from an AC Supply - Final Report". This report shows that the need for power factor correction circuits has been addressed and suitable topologies discussed in changes to IEC 555-2. Postage extra.

Mathematical analysis of the supply current waveforms likely to be drawn is performed. This allows theoretical analysis of circuit designs without breadboarding. The need for power factor correction circuits has been addressed and suitable topologies discussed. Conclusions are drawn and comparison of the harmonic content of the theoretical waveforms and the harmonics of a diode rectifier with reservoir capacitor are given in appendices. Also available as a 2-volume set with 91-0658D.
