Introduction

DC/AC converters are the core of power supply systems. The SHP 1000PS15, is a high-performance step-down DC-to-AC converter specifically designed for active input power factor correction applications such as LED lighting, HVAC and industrial automation. It provides an integrated solution to address today\'s tight power budget requirements in demanding applications.

The Features and Benefits of the SHP 1000PS15

The SHP 1000PS15 is designed to provide efficient and cost-effective power conversion for demanding applications. It contains a step-down regulator designed for active input power factor correction, with a maximum input voltage of around 600V. It also provides a wide range of voltage output ranges from 10 to 600V. The wide input voltage range, high efficiency, and low output ripple makes the SHP 1000PS15 well-suited for a number of demanding applications. The AC DC converter features a high efficiency of up to 95% and a wide input voltage range of up to 600 V, which allows it to easily power a wide range of loads. In addition, it is the first such converter to offer remote voltage programming via a CAN bus, which significantly simplifies mass production and maintenance in complex system designs. Finally, it features an adjustable output voltage (0-60 Volt) to ensure optimal power distribution across the entire system.

Working Principle of the SHP 1000PS15

The SHP 1000PS15 converter relies on a combination of step-down and active power factor correction circuitry to convert unregulated input voltage (up to 600 V) to a regulated output voltage (10 to 600 V). For input power factor correction, the input voltage is first stepped down by a buck regulator that reduces the input voltage to the operating voltage level desired by the load. This output voltage is then regulated by a synchronous buck regulator to control the output voltage.The active PFC circuitry then compensates for the effects of power factor load distortion in the AC mains by actively controlling the current drawn by the buck regulator circuit. This in turn helps to ensure that the active PFC modulation waveform largely matches the voltage waveform of the AC mains, resulting in better system efficiency.

Conclusion

The SHP 1000PS15 AC/DC converter provides an integrated solution for actively regulated, efficient, and cost effective power conversion applications. With its wide input voltage range, high efficiency and low output ripple, this converter is well-suited for active input power factor correction applications and offers remote voltage programming via a CAN bus for mass production and maintenance. Its active PFC circuitry helps to ensure that the modulation waveform of the converter matched the waveform of the AC mains, resulting in better system efficiency.
