Application Area

The PYB15-Q48-S15-H is suitable for electric noise from multiple sources, such as industrial equipment, medical, automotive and even military equipment. The converters can be used as a power source for many applications such as LED lighting, servo motors, instrumentation systems, fuel cells, UNIs, controllers, and various other motor-driven loads. It can also be used in systems where power conversion is required, such as in portable medical equipment, 48V telecom systems and computer applications.

Working Principle

The PYB15-Q48-S15-H power converter depends on a multi-stage converters topology. The core of the system consists of a transformer, an inductor, a rectifier, a switch tube, and a control circuit. First, the input DC voltage is rectified by the rectifier, and then the voltage is further processed by the switch tube in order to control the output voltage. Finally, the output voltage is then regulated by the inductor and transformer, thus providing a severe voltage and current regulation.

The converter is able to convert a high input voltage to a low output voltage, depending on the operation mode. In the buck mode, the input power is reduced and the output voltage is controlled by the switch tube. In the boost mode, the input voltage is increased resulting in a higher output voltage.

Overall

The PYB15-Q48-S15-H is a high voltage dual isolated DC converter designed for a wide range of input and output voltage applications. The wide input voltage range, PFC technology, full safety design, and wide input/output ripple voltage capability make the PYB15-Q48-S15-H an excellent choice for challenging power conversion applications. Most importantly, the working principle of the converter follows an advanced multi-stage converter topology that efficiently converts high input voltage to low output voltage with good control.
