The IGBT module PDMB200BS12C comes in several types, each with a certain function and application. These are some of the most common types:
CM
CM or conversing modular is a type of IGBT module, which consists of power transistors, ultrafast diodes, and a common collector. The IGBT provides a controlled switch of high power, while the diode is not conductive to current, and both are embedded in an epoxy resin for insulation. PDMB200BS12C is suitable for motor drives, induction heating, and switching power supplies.
FZ
FZ or field insertable modular conversant is another typical IGBT module. This one, however, consists of field replaceable power transistors and ultrafast diodes in a compact design. This module supports easy maintenance and replacement in the field. PDMB200BS12C in this category is used in power converters and industrial equipment.
BS
BS or half-bridge converter modular consists of IGBTs and diodes arranged into half bridge paths. This type of module allows simple connections to other circuit components. The half-bridge configuration provides the flexibility of building more complicated inverter types. Users employ this module in renewable energy applications and motor drives.
IS
IS or full-bridge insulated modules contain four IGBTs and four diodes with a plastic insulating base in between each. This type is known for its simple installation and electrical isolation between the power and control sides. It is utilized in welding equipment.
Following are the main features of PDMB200BS12C:
V(CEO)
The collector-emitter voltage is the maximum allowable voltage that can be applied between the collector and emitter terminals of the IGBT while keeping the device in the 'off' state. For the PDMB200BS12C, this value is 1200V.
V(EBO)
Similar to V(CEO), V(EBO) is the maximum voltage between the emitter and base terminal. It is called emitter-base voltage. It measures how much voltage can be applied between the emitter and base terminals of the IGBT while maintaining the device in the 'off' state. The PDMB200BS12C's V(EBO) is 3V.
I(C)
As PDMB200BS12C is a collector current power module, its maximum collector current is 200A. This is the maximum current value that can flow through the collector-emitter terminals of the device without damaging it.
I(B) or B(C)
The maximum base current for the IGBT module PDMB200BS12C is 12A, while B(C) or collector base current is 300mA. I(B) is the maximum current that can flow into the base terminal of the IGBT. B(C) is the maximum current that can flow out of the collector to the base terminal. B(C) is important for devices with limited base current requirements.
P(T)
The maximum allowable temperature for this power module is 150 degrees Celsius. P(T) is the maximum temperature that the module can reach without risking damage to the internal components.
t(ON), t(OFF)
PDMB can turn on or off within 300ns and 600ns, respectively. These are important parameters in applications that demand fast switching. They indicate how quickly the device can transition between on and off states.
Motor drives
In motor drive applications, the IGBT module PDMB200BS12C is used to control the speed and torque of motors, especially in demanding environments. These are space-efficient electronic components in motors found in industrial machines.
Salvageing equipment
Sensors make work easier and help companies save on tough jobs. PDMB modules help increase the efficiency and reliability of the equipment.
Industrial power supplies
These modules are employed in power supplies used in industrial settings to convert and regulate electrical power for different machines. They help ensure that these machines have a stable power supply for all their operations.
Renewable energy systems
In renewable energy systems like solar inverters, the PDMB200BS12C module helps convert and manage the electrical energy captured from the environment. This function is crucial for these systems to provide usable power. Without IGBT modules, solar panels wouldn't store or supply energy.
Welding apparatus
For welding machines, this module provides precise control over the IGBT's switching behavior. That's how it delivers the required power levels for different welding tasks. Its role in controlling the weld zone is crucial for good-quality welds. PDMB modules ensure that there is consistent welding and that there are no irregularities.
Induction heating systems
For induction furnaces, the PDMB200BS12C module is used to control the heating process. It efficiently converts electrical power to heat the desired items for use in metal working and materials.
Following are tips on maintaining and repairing IGBT modules:
Scrutiny
Regularly check the PDMB200BS12C modules for any visible wear, tear, or damage. Look out for signs such as burnt spots, cracks, or corrosion, as these could indicate that the module has been damaged. Checking for signs of overheating, for example, discolored areas, is also important.
Temperature monitoring
Ensure the cooling system around the module is working well. This helps to maintain the module at a safe operating temperature. Take note of the temperature thresholds and avoid exceeding them at any cost. Ex overheating will cause irreparable damage to the module.
Electrical checks
Regularly check the electrical connections for any looseness or corrosion. PDMB modules can suffer from electrical faults due to poor connection, spikes, or noise on the signal. Use filters or other noise-reducing devices to avoid electrical faults.
Functional testing
Regularly test the functions of the modules in the system to make sure they are working as they should. Good software modules enable companies to detect errors early and either fix or replace the faulty modules before they affect the system's overall performance.
Mechanical inspection
Check the supporting structures in which the PDMB modules are mounted to ensure they have not been subjected to unusual vibration. Excessive vibration can cause mechanical damage to the modules. Use anti-vibration mounts to safeguard the module against vibrations.
Firmware maintenance
For IGBT modules with programmable settings, make sure the firmware is up to date and properly configured to avoid operating the module defectively. Outdated firmware can limit electrical module functionality and performance.
The IGBT module PDMB200BS12C has the following quality and safety considerations:
Thermal management for quality and safety
Effective heat dissipation helps maintain module performance and reliability. Modules like PDMB200BS12C, which have cooling systems to aid in heat dissipation, reduce the risk of overheating and consequently prevent damage to the internal components. Proper thermal management extends the IGBT module's life and reduces fire hazards.
Electrical isolation for safety
The IGBT modules feature electrical isolation between the power and control circuits. This helps protect users from high-voltage electrical shocks. It also protects damage to other low-voltage equipment nearby. The isolation reduces the risk of electrical faults transferring from the power to the control side and vice versa.
Insulation materials
The materials used in IGBTs, such as epoxy resins, are good electrical insulators, minimizing the risk of unintentional short circuits. By preventing these phenomena, they reduce the risk of electrical breakdowns, which can be very hazardous, not just to the equipment but to the entire workspace.
Current monitoring
PDMB modules in current monitoring-based systems can detect abnormal current levels, high or low. They have built-in protection mechanisms that automatically shut down the module to prevent damage from overcurrent or electrical surges. This feature is pivotal in preventing electrical hazards, including fires, and protects the electronic components from potential damage.
