Isolators provide a reliable means of transferring information between circuits, protecting critical components from damage or malfunction by isolating load power from sensitive control electronics. The ACPL-3130-300E is a popular isolator Gate Driver, designed to drive IGBTs and MOSFETs. This article explains its application field and working principle.

The ACPL-3130-300E is a 4A Gate Driver that is compatible with a wide range of IGBTs and MOSFETs. It has a high output current drive with a fast rise and fall times, making it ideal for applications where high frequencies and short pulses are used. It also has built-in circuitry for fault protection, preventing damage to the device due to over-temperature, over-current, or under-voltage.

The ACPL-3130-300E is mostly used in power converters. As a high-speed, isolated Gate Driver, it is able to drive power devices with extremely fast switching times. It is commonly used in motor control, DC-DC or AC-DC converters, and uninterruptible power supplies (UPS). Additionally, it is used in automotive applications such as electric vehicles and hybrid electric vehicles.

The ACPL-3130-300E has the same isolation voltage as other ACPL Gate Drivers, making it suitable for high voltage applications up to 5.7kV. In addition to the built-in protection circuitry, it provides an external, configurable under-voltage lockout circuit, ensuring that the device will start up only when the power is within a safe range. Furthermore, it has an adjustable feedback voltage, providing flexibility in controlling the input voltage or speed.

The ACPL-3130-300E uses a dynamic bias technique to achieve high-speed switching. This technique uses the sensed current of the power device to control the voltage applied to the gate of the device. This ensures that the power device will be turned on and off quickly and efficiently. The ACPL-3130-300E also has an integrated reset circuit which ensures that there is no residual energy in the system when the power is turned off.

In summary, the ACPL-3130-300E is an isolated Gate Driver that is suitable for high voltage applications up to 5.7kV. It is widely used in power converters, motor control, DC-DC or AC-DC converters, uninterruptible power supplies (UPS) and automotive applications. The unit has built-in protection circuitry, an adjustable feedback voltage and a dynamic bias technique for fast switching times. It is an ideal solution for applications which require high reliability and quick response time.
