Bridge rectifiers are essential components in the power supply of many electronic products. The BU15105S-M3/45 is one commonly used bridge rectifier. It is a three-phase bridge rectifier module with high power density and high efficiency. This module is especially suitable for applications in the fields of motor control and lighting, such as air-conditioner, refrigerator, home appliances, and street lights.

The BU15105S-M3/45 is a key component of the power supply and supplies power to the other components in the circuit. It orrects the AC current and changes it into DC current. This is necessary for the circuit to work properly. The BU15105S-M3/45 is made up of four high-power silicon diodes, which are connected together in a bridge configuration. The bridge rectifier is composed of anode, cathode and anode, which are connected to the input power and output. The core of the bridge rectifier is the four diodes that are arranged in the shape of a bridge.

The BU15105S-M3/45 has a wide input voltage range, from 60V AC to 660V AC, and a high output current tolerance. It also has a fast response time and a wide operating temperature range, from -40°C to 85°C. Furthermore, the module has a built-in snubber network and surge absorption circuit, which help to reduce current and voltage spikes, thus increasing the life of the components.

The BU15105S-M3/45 has three main working principles. Firstly, the rectification principle. When an alternating current passes through the device\'s anode and cathode, the two main current paths are blocked and only the minor current paths are allowed to flow. As a result, the direction of the current is changed from alternating current to direct current.

The second is the voltage conversion principle. The input voltage is converted to a lower output voltage, which is necessary for the efficient operation of some components of the circuit. This is determined by the voltage drop of the diodes. Finally, the current ripple suppression principle is used to control the current ripples, which can cause damage to the circuit. The snubber network and surge absorbing circuit helps to reduce and control the current ripple.

In conclusion, the BU15105S-M3/45 bridge rectifier is a high-performance, high-efficiency, and cost-effective module, suitable for many different applications. It is easy to use, has a wide operating temperature range, and is able to withstand high currents. The main working principles are rectification, voltage conversion, and current ripple suppression. It is a safe and reliable device that can be used as a powerful and efficient power supply.
