The head mistress of a Secondary Modern School for girls had the good idea of organising a school party each year at the end of the summer term, the guests to be the pupils about to move up to ^e Senior school and the leavers to act as hostesses. It is difficult to tell which group derives the greater benefit, the 15-year-olds proudly showing the "little ones" around and enjoying their own uttp...

Starting strategies were investigated for a three-phase single-stage power factor correction (PFC) converter. Starting process and mechanism of input over current was analyzed in detail. A lossy method was proposed and designed in which a resistor was connected in series with the filter capacitor to increase effective value of output voltage. Based on them, the boost inductors were replaced by ...
