AC-DC converters are power electronic devices that change Alternating Current (AC) input to Direct Current (DC) output. AC DC Converters come in a variety of shapes, sizes, and applications ranging from everyday consumer products to industrial machines and automation processes. One such AC-DC converter is the ECM40US09, a single-phase Hybrid Active Power Factor Correction (PFC) with Bi-directional Soft-Switching (BSS) module.

The ECM40US09 is a versatile, dual-mode module with universal AC input and adjustable output voltage. Its adaptive on-board controller allows for fast line input voltage compensation, boosting the output power consistently under extreme operating conditions. The soft-switching control method eliminates the need for costly components and reduces the resonant switching losses, resulting in higher efficiency and longer module life. It also features an output current limiting and short circuit protection, making it an ideal module for industrial grade applications.

The working principle of the ECM40US09 module is based on a Full-Bridge (FB) topology with a dedicated PFC control block. The input current is supplied from the mains AC by a single phase full-bridge converter, rectified by a diode bridge. During the half-bridge commutation period, the main switch is always in the on state and the body-diode of the switch is conducting. The soft-switching bridge, connected to the main switch via an inductor, is also active during this period, allowing the current to flow directly to the output filter capacitor. During the OFF state, the soft-switching bridge is connected to the main switch, allowing it to be completely turned off.

The ECM40US09 module is designed for industrial applications that require high efficiency, high output power and low output voltage ripple. For these applications, the module can reach a peak efficiency of up to 97 percent at full load. The module can also be used in a wide range of power supply applications such as motor drives, uninterruptible power supplies (UPS), LED lighting, and communication systems.

In addition to its numerous applications in industrial power supplies, the ECM40US09 can also be adapted to solar applications. The on board controller can be used to regulate the maximum output power from the panel and the module can be regulated to reach a desirable output voltage and current. Furthermore, the module is equipped with an integrated PFC controller, providing high-efficiency solar-panel charging and decreased power losses.

The ECM40US09 module is an efficient and reliable AC-DC converter with a wide range of applications, from energy conversion to motor drives, UPS, lighting, and solar power. Its unique design allows it to achieve high efficiency and high output power, making it an ideal module for industrial or solar applications.
