AC DC Converters

The LPS173 AC DC Converter (LPS173) is a highly efficient, cost effective solution employed for regulating and converting alternating current (AC) to direct current (DC). It is an integrated power module ideal for multiple power conversion applications such as DC motor drives, air quality control systems, renewable energy systems, and various medical device applications. The LPS173 is designed to reduce system power loss, improve system efficiency, reduce energy consumption, and reduce thermal stress on surrounding components.

Design Features and Benefits

The LPS173 is a single-phase AC-DC power converter that features a number of innovative design innovations. These innovative design features ensure that the LPS173 offers superior power conversion and reliable operation.The LPS173 includes an integrated insulated gate bipolar transistor (IGBT) rectifier/converter. This feature eliminates the need to add an additional IGBT device, which reduces system costs and improves system efficiency. The integrated IGBT rectifier/converter also helps to reduce switching losses and improve current-sense accuracy, allowing for superior power conversion.Additionally, the LPS173 features a patented switching converter technology that enables the device to provide flexible system frequency operation. This technology enables the LPS173 to increase system output power while maintaining a low level of ripple and noise.

Working Principle

The LPS173 AC DC Converter works by converting AC voltage into DC voltage using an internal insulated gate bipolar transistor (IGBT) rectifier/converter. The LPS173 utilizes a patented switching converter technology that enables the device to output regulated DC voltage at a steady frequency. The device begins by converting the AC source voltage input into DC voltage using the IGBT rectifier/converter. The IGBT rectifier/converter then rectifies the alternating current into direct current. The DC voltage is then filtered by a low pass filter, which reduces switching losses and improves current-sense accuracy. The filtered DC voltage is then switched into an adjustable duty cycle electric signal. This signal is then used to drive an output voltage active regulator circuit which produces the regulated DC output voltage. The LPS173 active regulator circuit features adjustable voltage and current outputs, as well as adjustable frequency range.

Applications

The LPS173 AC DC Converter is designed for use in multiple power conversion applications, including dc motor drives, air quality control systems, renewable energy systems, and medical device applications. The LPS173 can be used to power appliances, testing and measuring instruments, medical equipment, and industrial systems that require DC voltage regulation. It is an ideal solution for applications where a highly efficient and cost effective AC-DC power converter is needed. In addition, the LPS173 is extremely efficient, allowing for up to 92% conversion efficiency in some applications. The device offers superior system power conversion, reduced system cost, improved system efficiency, reduced energy consumption, and reduced thermal stress on surrounding components. As such, it is a cost-effective and reliable solution for many industrial and commercial applications.
