Diodes - Rectifiers - Arrays, FML-22S Application Field and Working Principle

Diodes and rectifiers play a critical role in the operation of electrical circuits and are used in a wide variety of applications. The FML-22S rectifier array is one such device, providing multiple, highly efficient full wave rectification functions in a small, cost-effective package. In this article, we will discuss the application field of the FML-22S rectifier array, as well as the working principle behind it.

The FML-22S rectifier array is designed for use in applications such as power supplies, AC/DC converters, motor drives, and UPS systems. The device is a three-phase full-wave bridge rectifier, providing reliable, high-efficiency rectification of 24V to 600V AC input in a small, low-cost package. The array consists of four full-bridge rectification units integrated into one package, with each unit consisting of two series-connected rectifiers. The rectifiers in each unit are paired with fast anti-parallel diodes to ensure the full-wave rectification of the input voltage, eliminating the need for additional components.

TheFML-22S rectifier array features a wide variety of features and benefits that make it an attractive option for use in many applications. It provides a high surge capability of 3kA per unit and a high isolation voltage of 2kV, offering excellent protection against transients. It also features a low forward voltage drop of less than 1V and a low thermal resistance, offering a high power efficiency. In addition, the array offers flexibility, allowing for either series or parallel connection of rectifiers for additional current output capability. The FML-22S rectifier array is also capable of operating at a wide ambient temperature range from -25°C to +85°C, making it suitable for a variety of applications.

The working principle behind the FML-22S rectifier array is fairly simple. The device is composed of four full-bridge rectification units, each composed of two series-connected rectifiers. When an AC voltage is applied across the rectifiers in each unit, the diodes will conduct current in one direction in response to the changing polarity of the AC voltage. This will result in the rectification of the AC voltage, with the rectified voltage appearing across the output of the rectifiers. As the voltages in the circuit rise and fall, the diodes will switch on and off, allowing current to flow until the capacitor reaches the peak of the input voltage, and then blocking current flow until the voltage drops before starting the cycle again.

In conclusion, the FML-22S rectifier array is designed for use in a variety of applications, offering reliable and high-efficiency rectification of 24V to 600V AC input in a low-cost, small-sized package. The array consists of four full-bridge rectification units integrated into one package and employs fast anti-parallel diodes to ensure full-wave rectification of input voltage. It features a high surge capability of 3kA per unit, a low forward voltage drop of 1V or less, and a wide operating temperature range. The working principle of the device is mostly dependent on the rectifiers, which allow current to flow in one direction in response to the changing polarity of AC voltage, resulting in the rectification of the AC voltage.
