Power electronics technology is an important branch of next-generation electrical technology. It is widely used in electric traction, wind energy converter, high voltage DC transmission and military power system and other fields. The SL2.103 series AC DC converters plays a vital role in these fields.

SL2.103 is a three-phase rectifier DC power converter module that converts alternating current (AC) input to direct current (DC) output. It uses an innovative switch design to achieve a long life of 20k hours without ferrite core and excellent efficiency of up to 98.5%. The module adopts a two-stage resonant topology with a high-frequency link of 1MHz or 2.5MHz, enabling a wide input voltage and a high surge capability.In addition, SL2.103 AC DC converters have low output ripple noise and strong anti-impact ability.

SL2.103 series AC DC converters can be widely used in power supplies, battery charging systems, DC voltage stabilizing systems, industrial automation control systems, UPS (uninterruptible power supply) systems, motor drive systems, inverters, optoelectronic systems and solar systems.

SL2.103 AC DC converters have a wide input voltage ranging from 180V AC to 500V AC and output voltage up to 400V DC. Its maximum output power can reach 5kW and its efficiency can reach up to 98.5%. The output current is up to 30A and its switching frequency can reach up to 500kHz. With these features, SL2.103 series AC DC converters can meet the requirements of most power system projects.

The working principle of SL2.103 AC DC converters is based on a rectifier, inverter, and pulse-width modulator (PWM) concepts. The AC line input voltage is rectified into a DC voltage by diodes or rectifier bridges. This DC voltage is then filtered and regulated through a multistage DC/DC converter, such as a synchronous rectification boost converter, which then drives a switching element such as a power transistor. This inverter is then connected to the output voltage through a digital signal processor (DSP). This DSP controls the pulse width of the PWM circuit, thereby regulating the output current and voltage.

In summary, SL2.103 series AC DC converters provide an efficient and reliable DC power conversion solution for multiple applications. This series converters have a wide input voltage range, high efficiency, low output ripple noise, and high surge capability, making them the ideal choice for various power system projects.
