AC/DC converters are an essential component in many electronics applications, including communications, medical, automotive, and consumer applications. The HWS100A15/HD is a wide range of AC/DC converters developed by the Swedish company DPS AB. This article will discuss the application field and working principle of the HWS100A15/HD.

The HWS100A15/HD is a highly efficient power supply for electric motor drives, LED lighting systems, and industrial applications. It has a wide operating input voltage range of 85 to 265 Volts, which allows it to be used with both AC and DC power supplies. Its switching frequency of 100 kHz enables it to provide a high power conversion efficiency of 95%. The HWS100A15/HD also has a small size and lightweight body, making it well suited for applications in which size and weight are a consideration.

In addition to its high efficiency and small size, the HWS100A15/HD has several other features that make it ideal for motor and LED lighting applications. These include its high efficiency at low and medium loads, its excellent output noise performance, and its wide temperature range. It also features an overload protection circuit that helps protect against short circuits.

The working principle of the HWS100A15/HD is based on a switch-mode approach. The power supply acts as a voltage/frequency converter, converting the input voltage and frequency to the desired output voltage and frequency. This is achieved by using a series of transistors arranged in a parallel fashion. When a voltage is applied to the transistors, they draw a certain amount of current and generate a switching frequency that is proportional to the input voltage. This switching frequency is then converted to the desired output voltage and frequency.

The overall efficiency of the HWS100A15/HD is also improved by active power factor correction (PFC). This technology uses an additional switch that varies the current flowing through the switching transistors as a function of the input voltage. This helps to reduce the power losses associated with the switching transistors, resulting in higher efficiency levels. The HWS100A15/HD also features a built-in thermal protection circuit that helps protect the power supply from thermal overloading.

In conclusion, the HWS100A15/HD is a highly efficient and reliable AC/DC converter designed for use with both AC and DC power supplies. It has a wide operating input voltage range, a high conversion efficiency of 95%, and a small size and lightweight body. It also features an overload protection circuit, active PFC, and a built-in thermal protection circuit. These features make the HWS100A15/HD an ideal choice for motor and LED lighting applications.
