drive circuit การใช้

• The drive circuit was formed by low-temperature polysilicon TFTs.
• A polarity controlled relay needs changeover switches or an H bridge drive circuit to control it.
• DC-to-DC voltage doublers cannot switch in this way and require a driving circuit to control the switching.
• Also, the driving circuit can have silicon diodes mounted in thermal contact with the output transistors to provide compensation.
• A separate frequency determining drive circuit gives you independent and therefore greater control over a multitude of circuit parameters.
• The drive circuit surrounds the device and a large circular conductor attaching to the edge of the IGCT is used.
• JMAG is used actively to analyze designs at a system level that includes drive circuits by utilizing links to power electronic simulators.
• This device can be turned on by a pulse provided by a driving circuit, but cannot be turned off by removing the pulse.
• The main differences are a reduction in cell size, and a much more substantial gate connection with much lower inductance in the gate drive circuit and drive circuit connection.
• The main differences are a reduction in cell size, and a much more substantial gate connection with much lower inductance in the gate drive circuit and drive circuit connection.
• Care must be taken to ensure the tuning range of the driving circuit ( for example, a voltage-controlled oscillator ) must fall within the input locking range of the ILFD.
• The usual setup is to have a positioning controller, known as an " indexer ", sending step and direction pulses to a separate higher voltage drive circuit which is responsible for commutation and current limiting.
• The Mark IIC + was the last of the Mark II series and featured a more sensitive lead channel, because it features a dual cascading drive stage, whereas the IIA and IIB had a single stage drive circuit.
• In the announcement, Circuit City offered a brighter prognosis for its fourth quarter, but the news of the restructuring rattled investors, driving Circuit City's shares down 5 11 / 16, or 17 percent, to 26 15 / 16 Tuesday afternoon.
• The very high gate currents and fast dI / dt rise of the gate current mean that regular wires can not be used to connect the gate drive to the IGCT . The drive circuit PCB is integrated into the package of the device.
• Having only 3 electrode types ( a filament, an anode and 10 different grids ), the driving circuit for this tube was very simple, and as the image was projected on the glass face, it allowed a much wider viewing angle than for example nixie tubes which Nimo tried to replace.
• Each hammer was moved by a powerful electromagnet, with its coil connected to a high current drive circuit, such that the hammer could be forced out to hit the paper within only a few milliseconds, at exactly the right time to strike the correct character on the chain as it came by.
• Stack-type SBCs often have memory provided on plug-cards such as SIMMs and DIMMs . Hard drive circuit boards are also not counted for determining if a computer is an SBC or not for two reasons, firstly because the HDD is regarded as a single block storage unit, and secondly because the SBC may not require a hard drive at all as most can be booted from their network connections.
