Description
ABB power module features and applications ABB power module uses advanced integrated circuit technology to integrate power devices and logic control circuits in a highly integrated, fully sealed integrated block with power function. The power module has the advantages of convenient use and reliable performance, which represents the development direction of power supply technology. Because the switching power supply has the advantages of high efficiency and small size, it is suitable for integration. Because of its low efficiency, generally about 50%, it is difficult to achieve high-power (more than 100W) integration. The power module introduced by Jimi technology refers to the switching power module, focusing on the DC/DC converter. Today's switching power modules can reach hundreds of watts or even kilowatts. Power module products mainly include DC/DC converter module, power factor correction module, AC input module, etc. Their main characteristics are: ◆ ABB power module working frequency is high, generally 300KHz~1MHz. ◆ ABB power module size is small, ultra-thin, thickness is generally less than 20mm, light weight, generally less than 200g. ◆ ABB power module power density is large, generally 5~10W/ cubic centimeter. ◆ ABB power module is easy to use, less external components, can be expanded in parallel, and can also realize logic control and remote control. ◆ ABB power module is suitable for a wide range of power grid voltage changes. When the general AC voltage fluctuates between 150V and 280V, the output has a voltage regulator function. ◆ ABB power module temperature adaptation range is wide, can be from -55 degrees Celsius ~+100 degrees Celsius, the general high temperature substrate temperature is +85 degrees Celsius, low temperature 0 degrees, -20 degrees, -40 degrees, -55 degrees and other levels. ◆ ABB power module fully sealed package, with three anti-function, waterproof, dustproof, anti-impact. ◆ ABB power modules generally use zero voltage switch or zero current switch technology, good electromagnetic compatibility. ◆ ABB power module structure is highly standardized and easy to install.
Silicon Controlled Rectifier (SCR) is a high-power electrical component, also known as a thyristor. It has the advantages of small size, high efficiency and long life. In the automatic control system, it can be used as a high-power driving device to realize the control of high-power equipment with low-power control. It has been widely used in AC and DC motor speed control system, power regulation system and servo system. Thyristors are divided into two kinds: unidirectional thyristors and bidirectional thyristors. Bidirectional thyristor is also called TRIAC, or TRIAC for short. The bidirectional thyristor is structurally equivalent to two unidirectional thyristors in reverse connection, and this thyristor has a dual pilot pass function. Its on-off state is determined by the control pole G. Adding a positive pulse (or negative pulse) to the control pole G can make it forward (or reverse) conduction. The advantage of this device is that the control circuit is simple and there is no reverse voltage problem, so it is particularly suitable for AC contactless switch use. P1N1P2N2 four-layer three-terminal device with silicon single crystal as the basic material began in 1957, because its characteristics are similar to vacuum thyristor, so it is known internationally as silicon thyristor, referred to as thyristor T, and because the thyristor was originally in static rectification, it is also known as silicon controllable rectifier element, referred to as thyristor SCR. In terms of performance, thyristor not only has unidirectional conductivity, but also has more valuable controllability than silicon rectifier elements (commonly known as "dead silicon "). It only has two states: on and off. SCR can control high-power electromechanical equipment with milliampere-level current, if the power exceeds this, due to the significant increase in component switching loss, the average current phase allowed to pass is reduced, at this time, the nominal current should be degraded. Thyristor has many advantages, such as: to control high power with small power, power amplification up to hundreds of thousands of times; The response is extremely fast, opening and closing in microseconds; No contact operation, no spark, no noise; High efficiency, low cost and so on. The weakness of thyristor: static and dynamic overload capacity is poor; Easily misled by interference. Thyristor from the appearance of the main classification: bolt shape, flat plate shape and bottom shape.
