the thyristor
In the course of thyristors thyristor T, and its anode A and lubricated plug valve cathode K with the power and load connections alnico magnet main circuit composed of thyristors, thyristor gate G and cathode K thyristor power inverter device connection and control, composition thyristor control circuit.
SCR working conditions: fag bearing Thyristor withstand reverse anode voltage, no matter what the gate withstand coaxial cable voltage thyristor are in pigment red 122 the off state. 2. Thyristor to withstand a positive anode voltage, t he only gate to bear in auto ac compressor the case of thyristor forward residual current circuit breaker voltage was turned on. 3. Thyristor in conduction case, as long as there is a certain safety relief valve positive anode voltage molded case circuit breaker regardless of how the gate voltage optical frames thyristor remains on, the thyristor, the gate useless. 4. Thyristor in coffee table conduction case, when the main circuit voltage (or current) is reduced to near zero, the thyristor off.
Edit this paragraph school playground equipment from the working process spring rider of internal analysis of the thyristor Its main features, plus the bag making machine negative when the gate thyristor steam trap trigger signals on their own time ball valve off. Intelligent modules thyristor As mentioned above, ordinary thyristor jet lighter (SCR) is triggered by the door after a very positive signal, the signal can be maintained on-state removed. Meant to make the turn-off coin sorter we must cut off the power, so that the forward cheap nfl jerseys current below the holding current IH, or subjected to strong near outsourcing cost savings turn-off reverse voltage. This need to increase the 304 stainless steel plate commutation circuit, not only the size of the weight of the equipment dancing fountain increases, it will reduce efficiency, resulting in waveform distortion and noise. GTO overcome these shortcomings, both retained pigment red 57:1 the general thyristor high voltage, current pigment yellow 74 big advantages to self-shutdown capability, easy to use, is ideal for pigment red 2 high-voltage, high current switching devices. GTO capacity and service life of more than a giant transistor (GTR).
GTR is lower than the work carton sealer of spinning frequency. Currently, GTO has reached air circuit breaker 3000A, 4500V capacity. High-power GTO has been widely forged valve used in chopper speed control, frequency control, power inverter, and other fields, showing strong vitality. GTO igbt module also belongs to PNPN four three-terminal device, its structure and the same equivalent circuit and the swing sets eneral thyristor, the GTO Figure 1 plots only the shape of typical products and symbols. Most module form made of steam trap high-power GTO. Although the GTO and the SCR trigger turn-on the same principle, but the shutdown of both principle pneumatic valves and way off completely different. This is due to normal after the thyristor in conduction in the depth pressure reducing valve of saturation is outside, and GTO in turn can only be achieved after the critical saturation, so the GTO gate add to the swing sets negative trigger signal can be turned off. An important parameter is the GTO turn-off gain, βoff, which is pigment red 21 equal to the maximum turn-off anode current IATM with the largest negative gate current IGM ratio, having the formula moncler jackets usually several times lv shoes or more. βoff larger value, indicating that the gate current on the nike air max 2009 anode current control stronger. Obviously wedge anchor prosperity hFE parameters quite similar.
The following were introduced by hydraulic pump the multimeter to determine GTO electrode, check GTO turn-off triggering capabilities and ability to estimate the turn-off gain βoff method.
