The origins of Shindengen go back to Dengensha, a manufacturer of electric stoves and rectifiers founded in 1935. In 1944, Dengen Kogyo Co., Ltd. was created by Dengensha to meet the high demand for selenium rectifiers for use by the military during the war in the Pacific. After the war, the company continued to produce rectifiers for both the ...
Whereas normal semiconductor diodes have a roughly fixed voltage drop of around 0.5 to 1 volts, active rectifiers behave as resistances, and can have arbitrarily low voltage drop. Historically, vibrator -driven switches or motor-driven commutators have also been used for mechanical rectifiers and synchronous rectification.
Some voltage-regulator tubes contained small amounts of radionuclides to produce a more reliable ionization. [ 1 ] The Corona VR tube is a high-voltage version that is filled with hydrogen at close to atmospheric pressure, and is designed for voltages ranging from 400 V to 30 kV at tens of microamperes.
An active regulator employs reactive components to store and discharge energy, so that most or all current supplied by the rectifier is passed to the load. It may also use negative and positive feedback in conjunction with at least one voltage amplifying component like a transistor to maintain output voltage when source voltage drops.
The nation said a proper farewell to former President Jimmy Carter during his funeral service in Washington D.C. on Thursday. President Joe Biden, who declared Thursday a national day of mourning ...
The ferroresonant transformer, ferroresonant regulator or constant-voltage transformer is a type of saturating transformer used as a voltage regulator. These transformers use a tank circuit composed of a high-voltage resonant winding and a capacitor to produce a nearly constant average output voltage with a varying input current or varying load.
The Chicago Bears have finally made a change after this weekend's awful 19-3 loss to the New England Patriots. The Bears announced Tuesday morning that offensive coordinator Shane Waldron is out ...
A Detroit pastor told Fox News Digital that it is "impossible" for pastors and Christians to be politically "neutral." "The gospel message is a political message. The Bible is a political book ...
