AC/DC converters are an important class of power conversion devices that allow the conversion of AC power into DC power. The CUS100ME18/B is an ultra-wide input AC/DC converter which is widely used in a variety of applications, including UPS, Personal Computers, Telecom Equipment, Automotive, Lighting, and Medical Equipment, to ensure the smooth transition of power.

The CUS100ME18/B converter has a selection of configurable features, including power levels of up to 100W, wide input voltage of 70 – 264V and a wide temperature rating of -40 to +90°C. In addition, the device offers very low power consumption in standby mode, both no load and full load efficiency up to 94%, and built-in safety features for operations in critical applications including Overcurrent Limiting, Overvoltage Protection, and Over Temperature Protection.

The working principle of CUS100ME18/B AC/DC converter is based on the so-called flyback topology. The AC input is rectified to create a DC voltage which is stepped up to the required DC output voltage. The high voltage is then regulated and returned to the input using a series of switching operations using a power transistor operating as a switch. The transformer stores the magnetic energy during the first half of the cycle, and it releases the energy to the load during the other half of the cycle. The output voltage is regulated without the need of feed back control, by using an isolated transformer and a pulse width modulation (PWM) control.

CUS100ME18/B AC/DC converters offer a wide range of features that make them suitable for a wide range of applications. This includes a low component count, a high operating temperature range, low power consumption, and a wide range of input voltages. Moreover, the device has built-in safety features, making it suitable for use in critical applications. The CUS100ME18/B also offers excellent no-load and full load efficiency, making it an ideal choice for most power conversion applications.
