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.
Characteristics of thyristors
(1) bidirectional conductivity
Thyristors have bidirectional conductivity, that is, they can conduct current at both forward and reverse voltages. This allows thyristors to be used in AC and DC circuits to achieve bidirectional current control.
(2) Switching characteristics
The thyristor has the switching characteristic, that is, under the action of the control voltage, it switches from the off state to the on state. Once the thyristor is switched on, it remains switched on until the current drops to zero or is disconnected by an external control. This switching characteristic enables the thyristor to realize efficient current switching control in the circuit.
(3) Trigger control
The on-state of the thyristor can be controlled by triggering the current. When enough current is applied by the Gate, the thyristor switches from the off state to the on state. This trigger control allows the thyristor to precisely control the on-off of the current in the circuit.
(4) High current and voltage tolerance
Thyristors can withstand considerable current and voltage. This makes it suitable for high power circuits and power control systems, such as motor control, power converter and other fields.
(5) Fast switching speed
The thyristor has a fast switching speed and can be switched from the off state to the on state in a nanosecond. This makes it suitable for high frequency applications such as variable frequency speed control systems.
(6) Stability and reliability
The switching and control of thyristor is based on physical principle, so it has high stability and reliability. It is not susceptible to external interference or temperature changes.
(7) Energy saving and efficiency
Because of the fast switching speed of thyristors, fast current switching can be realized in the circuit, thus reducing energy loss and improving the efficiency of the circuit.
