CM75E3U-24H is a metal-enclosed isolation module with a combination of a power IGBT and a freewheeling diode. It is made for use in a variety of industrial applications, most notably in motion control systems and electric motor drives. In this article we will explore the working principle and application field of the CM75E3U-24H.

Working Principle

The CM75E3U-24H is a thyristor power conversion module with a pair of N-channel IGBT\'s and a pair of freewheeling diodes. The IGBT\'s are used as switches to control power flow, while the freewheeling diodes provide parallel current paths to reduce voltage stress when the load current is reversed. The module also contains a common emitter resistor to limit the maximum dc collector current and a snubber circuit to reduce the dv/dt transients.

When the gate drive is applied, the base current for IGBT turns the device on, allowing current to flow through the collector-emitter terminals of the IGBT. At the same time, the freewheeling diode is forward biased, allowing current to flow from the collector to the emitter in the opposite direction of the IGBT current. The two current paths are added together to provide the total current flowing through the module.

Application Field

The CM75E3U-24H is used in a wide variety of industrial applications, most notably in motion control systems and electric motor drives. In these applications, the module is used to control the speed and direction of a motor by controlling the power flow. The IGBT\'s are used to switch the power to the motor in a controlled manner, while the freewheeling diodes provide protection from voltage transients during the switching process. This provides a safe and efficient way to control motor speeds.

The CM75E3U-24H is also used in a variety of other applications, such as SCR DC drives, DC to AC inverters, UPS systems, and AC servo regulators. In each of these applications, the module is used to control power flow in a safe and efficient manner.

The CM75E3U-24H offers many advantages over other modules, such as superior thermal performance, higher current handling capability, high isolation voltage, and a compact size. This makes it an ideal choice for many industrial applications.
