AC DC converters refer to electronic power converters used to convert alternating current (AC) into direct current (DC). AC DC converters can be further classified into two categories, namely switch-mode power converters and linear power converters. Switching converters have high efficiency, low size, and low weight but at the expense of high electromagnetic interference noise, while linear converters, comparatively, have low efficiency, high size, and high weight but with low noise. In this article, we will focus on an AC-DC converter called KMS15-9 and discuss its application field and working principle.

KMS15-9 is a high-efficiency, low-noise, compact and low-cost AC-DC converter. It is made up of two components; a full-wave bridge rectifier and a linear integrated regulator, along with critical components such as inductors, capacitors and transformers. The most distinct feature of KMS15-9 is its ability to convert AC input power into DC output power with sufficient efficiency and high accuracy. This makes KMS15-9 is ideal for applications such as portable electronic devices, battery chargers, portable medical devices, and other similar DC power applications.

The working principle of KMS15-9 is quite simple and can be divided into 3 stages. Firstly, the AC mains power is rectified by the full-wave bridge rectifier, creating a rectified and filtered DC signal. Secondly, the DC signal is regulated and stabilized by the linear integrated regulator. Lastly, a primary transformer is used to reduce the ripple and boost the output voltage.

KMS15-9 also has a wide input voltage range, low ripple, and low noise output. This makes it suitable for a variety of DC power supply applications which require higher DC voltage than the input AC voltage, such as portable electronic devices, battery chargers, portable medical devices and other similar DC power applications. Additionally, the built-in EMC filter makes it suitable for applications which require electrical interference protection.

In summary, KMS15-9 is an efficient, low-noise, compact, and low-cost AC-DC converter, highly suitable for DC power supply applications. Its wide input voltage range, low ripple, and low noise output makes it an excellent choice for applications requiring high DC voltage from an input AC signal. Additionally, its built-in EMC filter offers superior electrical interference protection. Thus, KMS15-9 is well suited to be used in a variety of applications such as portable electronic devices, battery chargers, portable medical devices and other similar DC power applications.
