9001 Series Over Current Detector Circuit Examples
... In this circuit, current must be sensed in the bridge to protect the power transistors against over current conditions. The over current conditions can be caused by transient loads on the output of the inverter, or shoot through conditions caused by noise in the control circuitry or intermittent log ...

Two different slopes (green and blue boxes) can be distinctly observed during cooling (no actuator current) and heating periods, with punctuated transitions in between. The current-dependant effect is most marked at 72 ºC (black circ ...

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.
