The second amplifier released was the Phase Linear 400 with 200 watts per channel. It shared the same distinctive brushed aluminum, dual VU meters front panel style as the 700. It retailed for just under $500. [1] The next product was the Phase Linear 4000 Series Auto-correlation Pre-Amplifier introduced in 1973 and manufactured through 1978.
He is known for designing the Phase Linear 700, at 350 W per channel the most powerful consumer audio amplifier available in 1972. He went on to found the Carver Corporation in 1979, Sunfire in 1994, and the Bob Carver LLC in 2011 [2] which was sold to Jade Design in June, 2013. [3]
For example, balanced two-phase power can be obtained from a three-phase network by using two specially constructed transformers, with taps at 50% and 86.6% of the primary voltage. This Scott T connection produces a true two-phase system with 90° time difference between the phases.
In electronics, power amplifier classes are letter symbols applied to different power amplifier types. The class gives a broad indication of an amplifier 's characteristics and performance. The first three classes are related to the time period that the active amplifier device is passing current, expressed as a fraction of the period of a ...
Non-linearities occur in amplifiers due to decreasing amplification and changing phase when operated near saturation. This behavior is commonly referred to as gain or phase compression. The pre-distortion linearizer is designed to compensate these changes. The resulting behavior is commonly referred to as gain or phase expansion.
Zero-phase-sequence current transformer Ring-type current transformers are installed over a bus bar or an insulated cable and have only a low level of insulation on the secondary coil. To obtain non-standard ratios or for other special purposes, more than one turn of the primary cable may be passed through the ring.
Converted from three-phase 6600 V 25 Hz in 1927, dismantled 1956 United States: Colorado: Denver and Intermountain Railroad: dismantled c. 1953 [35] 12 kV: 16 + 2 ⁄ 3 Hz France: lines in Pyrenees: Chemin de fer du Midi: most converted to 1,500 V 1922–23; Villefranche-Perpignan diesel 1971, then 1,500 V 1984 12 kV: 25 Hz United States
In contrast, a linear power supply regulates the output voltage by continually dissipating power in the pass transistor. The switched-mode power supply's higher electrical efficiency is an important advantage. Switched-mode power supplies can also be substantially smaller and lighter than a linear supply because the transformer can be much smaller.
