AC/DC converters, commonly known as rectifiers, are electrical devices that convert alternating current (AC) into direct current (DC). The TXM 035-115 is one such converter that has various applications in a range of industries and is capable of supplying over 115 Amperes of continuous current. This article will discuss the application field and working principle of the TXM 035-115.

The TXM 035-115 is a highly efficient three-phase, input AC/DC converter module. It is typically used in a wide variety of applications such as electric vehicle charging stations, medical equipment, and military systems. It is highly reliable and can operate up to 105 degrees Celsius. It is certified for EMI and safety compliance, and also supports global AC mains operations.

The working principle of the TXM 035-115 converter is based on bridge rectifier circuits. This uses a three-phase AC input and four blocking diodes to produce a direct current output. The four diodes in the bridge form two rectifying circuits, which act as a full-wave rectifier, rectifying the positive and negative waveforms of the AC sine wave. This rectifying circuit is used to convert the AC waveforms to a pulsed DC waveform, with the voltage converting to the desired output. The output voltage is equal to the source of the AC/DC converter minus the forward voltage drops of the diodes.

The TXM 035-115 also features short-circuit protection circuitry, which uses a fused current sensor to detect the fault current. If the fault current does exceed the maximum set, then the controller will shut down the power to the output, protecting the upstream circuit from any potential damage. The control is handled by a microcontroller that monitors the input voltage, output voltage, and output current, and adjusts the conduction patterns of the AC switches accordingly to keep the output voltage and current within the required limits.

The TXM 035-115 also comes with over-current and over-voltage protection circuitry, which helps to protect the device from potential damage. In case of an over-voltage or over-current situation, a signal will be sent to the controller which will then shut down the power to the output and activate an alarm signal. The entire system can be remotely monitored via a communication network such as CANbus or Modbus, providing real-time information of the process.

The TXM 035-115 is a comprehensive application-specific product with hardware and software designed for the specific purpose of AC/DC conversion. Its high efficiency, reliability, and flexibility make it a versatile converter suitable for a wide variety of applications. It can accept an AC input voltage, rectify it, and regulate the output voltage and current to meet the customer’s needs. Its protection circuitry makes it a safe and reliable product, making it an ideal choice for many applications.
