Diodes - Rectifiers - Arrays are used in modern electronic systems for a variety of purposes. One of the most common applications is the DSP8-12AC, a rectifier array used for a range of applications. This article will discuss the application field, working principle and advantages of the DSP8-12AC.

Applications

The DSP8-12AC rectifier array is commonly used to rectify AC power, accept voltage levels of up to 400V and provide a DC output. It is suitable for a wide range of applications such as lighting, energy saving and output rectification, industrial converter, AC/DC power supply, LED power supply, internet power supply, automotive power supply and digital products. Additionally, the device provides EMI filtering functions, soft start and diode protection.

Working Principle

The DSP8-12AC is a bridge type rectifier array produced by Dasbridges Electronics Co. with a synchronous rectifying technology. Its working principle is based on the active body diode (ABD) power switch, which is a P channel MOSFET that can be programmed to switch states with a frequency of up to 5MHz. This technology is integrated into the DSP8-12AC and helps to reduce switching losses, minimize EMI and reduce cost.

The DSP8-12AC consists of eight independent bridges in parallel, each containing 12 diodes. The bridgeless design achieves fast switching times and a divided voltage supply. Each bridge is matched to reduce forward voltage drop, improve power efficiency and ensure enough output current margin.

Advantages

The DSP8-12AC rectifier array is suitable for a variety of applications due to its small size, low cost and high efficiency. The ABD power switch technology requires less energy than traditional rectifier technologies and allows for higher efficiency rates. The device’s robust design is suitable for long-term use in harsh environments, with low power losses even at high junction temperatures and a wide input voltage range up to 400V. The synchronous rectifying technology also reduces EMI and allows for a wide duty cycle range.

Overall, the DSP8-12AC rectifier array is a versatile, low cost and efficient solution for rectifying AC power. The device’s bridgeless design offers fast switch times, reduced forward voltage drop and improved power efficiency. Additionally, its ABD power switch provides low power losses and EMI protection, allowing it to be used in a wide range of applications.
