Power Factor Correction
Power Factor Correction

... incoming AC, the higher the power factor it will have and the less AC power it will consume. With less incoming AC power required by the converter there is more available AC power available for a microwave, TV and other AC loads on the RV. The power factor correction (PFC) circuit is designed to dra ...

Valve RF amplifier



A valve RF amplifier (UK and Aus.) or tube amplifier (U.S.), is a device for electrically amplifying the power of an electrical radio frequency signal.Low to medium power valve amplifiers for frequencies below the microwaves were largely replaced by solid state amplifiers during the 1960s and 1970s, initially for receivers and low power stages of transmitters, transmitter output stages switching to transistors somewhat later. Specially constructed valves are still in use for very high power transmitters, although rarely in new designs.
