AC DC Converter – ZWS75BAF-3/A Application Field and Working PrincipleThe AC/DC converter, also known as a DC/DC converter, is one of the most important components in AC/DC system technology. A good understanding of its working principle is essential for the design and operation of these systems. ZWS75BAF-3/A is a typical AC/DC converter, one of the series of switching converters developed by ZETAC. This paper mainly studies the application field and working principle of the converter.ZWS75BAF-3/A converter is a DC/DC converter with high efficiency and high reliability, and mainly applicable to the DC power supply with power output up to 75W. This series of switching converters can accurately control the DC output voltage, and with voltage and current waveform stability. Furthermore, these converters have strong short-circuit protection and overload protection. The maximum power output of the ZWS75BAF-3/A switching converter can reach 75W.The circuit core LCD control loop of the ZWS75BAF-3/A switching converter is composed of a transformer, a diode, an inductor, and a mosfet. As shown in Figure 1, the primary side of the transformer input AC power is rectified and filtered by the diode and the capacitor. The filter output produces a DC voltage, and this DC voltage is switched by the mosfet periodically. The inductor acts in the same way as an accurately measured capacitor with varying amperage. The features of this loop are such that current and voltage waveforms are stable.Figure 1. AC/DC Converter SchematicThe output voltage of the switching converter is regulated after a full rectification by the LC filter. The filter can effectively suppress the high-frequency noise and generate the stable DC voltage. Furthermore, the external sense voltage is used to regulate the output voltage in order to obtain an exact output voltage.The electronic protection devices are adopted in the ZWS75BAF-3/A switching converter. The device such as SCR will be triggered to protect the converter from short circuit current. Besides, the over-current protection will be activated according to a given voltage.The ZWS75BAF-3/A switching converter is suitable for the applications that require high-efficiency switching DC/DC converter with power output up to 75W. The operating voltage range is from 6 to 32VDC, and the output voltage range is from 0.8V to 32VDC. It is mainly used in the fields of communication electronics, control system machinery, medical instrument, solar power, automotive electronics, automatic meters and other high-power product.To sum up, as an important part of the AC/DC system technology, ZWS75BAF-3/A switching converter has the advantages of precise voltage and current waveform stability, strong protection, and wide operating voltage and output voltage range. It is suitable for various applications and enjoys a wide range of use.
