pulse transformer การใช้

• The regulator controls the switching transistors insulated by optocouplers or pulse transformers.
• The common mode voltage is easily extracted using the center tap of the standard Ethernet pulse transformer.
• The support structure positioned and supported the vacuum tank which also shared the same spherical center as the large pulse transformer.
• For example, a pulse transformer creates rectangular pulses, which are characterized by fast rise and fall times with a flat top.
• MPP cores are primarily used in inductors that require a core to have higher pulse transformers, and other industrial and military circuits.
• Multiple layers of thin dielectric films are used where maximum practical dielectric strength is required, such as high voltage capacitors and pulse transformers.
• The main components that comprised START included the support structure, pulse transformer, vacuum tank, toroidal and poloidal field coils, and a limiter.
• With the increasing trend towards digital processing and transmission of audio signals, the full range of isolation by small pulse transformers, optocouplers or fibre optics become more useful.
• To minimize distortion of the pulse shape, a pulse transformer needs to have low values of leakage inductance and distributed capacitance, and a high open-circuit inductance.
• The product of the peak pulse voltage and the duration of the pulse ( or more accurately, the voltage-time integral ) is often used to characterise pulse transformers.
• The main role of the pulse transformer was to provide the current for the toroidal field coils which was supplied through fifteen irons cores that were spirally wound from a . 03 millimeter iron strip.
• Pulse transformers by definition have a duty cycle of less than 0.5; whatever energy stored in the coil during the pulse must be " dumped " out before the pulse is fired again.
• In power-type pulse transformers, a low coupling capacitance ( between the primary and secondary ) is important to protect the circuitry on the primary side from high-powered transients created by the load.
• A pulse transformer is typically required when driving higher impedance devices such as klystrons or magnetrons from a PFN . Because the PFN is charged over a relatively long time and then discharged over a very short time, the output pulse may have a peak power of megawatts or even terawatts.
• Bobeck was born in Tower Hill, Pennsylvania, received his B . S . ( 1948 ) and M . S . ( 1949 ) degrees in electrical engineering from Purdue University, and in 1949 joined Bell Laboratories where he helped design communication and pulse transformers, and then one of the first solid-state digital computers.
