A new three-phase off-line switching AC/DC converter is described, one which draws essentially sinusoidal AC currents from the input line and therefore generates a very low TIF (Telephone Influence Factor) in the three-phase line currents. The converter consists of three two-stage power processors, the first stage of each performing the unity power factor(More)
The effects of battery and distribution impedance on battery charger dc output noise is considered for various capacitor and inductor output filters. The importance of distribution bus and "battery loop" inductance is demonstrated and it is shown that the improved filtering expected from larger ampere-hour batteries may not be realized. Methods to calculate(More)
A new DC to AC inverter concept has a single switching stage followed by a linear amplifier. It provides input to output isolation, circuit simplicity, ruggedness and low manufacturing cost. It is equally suited for operation at low power levels (i.e. ringing generators) and at higher powers since Darlington Transistors or Gemfets can be used in the low(More)
A study of patents, publications, and applications indicates the first design and application of a "Scott-T Connected Inverter" was made by Warren Communications in 1972. The first installation of record was a 30-KVA inverter system now installed and operating at the Barkeley Bank in Jamaica. Since 1972, other companies are manufacturing inverters with this(More)
