DC DC converters are versatile components used in a variety of applications. This article will provide an overview of the QSC15024S24 family of DC DC converters, their application field, and their working principle. The QSC15024S24 family is a series of DC DC converters designed for use with AC line-powered circuits. These converters are typically used in industrial applications, such as power supplies, automotive applications, and backup systems. The series is available in a variety of wattages, ranging from 15W to 24W, and offers a wide input range of 90-240 VAC. The AC and DC output ratings are as follows: DC voltage range: 12-24V, maximum current: 7A, and peak output power: 24W.The design of the QSC15024S24 family of DC DC converters mainly consists of three parts: the primary stage, the secondary stage, and the control circuit. The primary stage is composed of input voltage rectifying circuit, EMI filter, inrush current limiting circuit, and a DC-DC converter. The rectifying circuit is used to rectify the AC input voltage into a DC voltage. The EMI filter is used to reduce any harmonic voltages generated by the primary stage. The inrush current limiting circuit is used to limit the inrush current during start-up. The DC-DC converter is used to convert the DC input voltage to the specified DC output voltage. The secondary stage consists of a DC output voltage regulation circuitry, isolation transformer, and output voltage monitoring circuit. The DC output voltage regulation circuitry is used to regulate the DC voltage to a specified level. The isolation transformer is used to isolate the input from the output, ensuring a safe operating environment. The output voltage monitoring circuit is used to monitor the output voltage to ensure that it remains within the specified range. Finally, the control circuit is used to control the operation of the DC DC converter. It consists of a micro-controller, which is used to control the operation of the DC DC converter. It also contains a power-on reset circuit, a thermal shutoff circuit, as well as an over-current protection circuit. In conclusion, the QSC15024S24 family of DC DC converters offers a wide range of power ratings and voltages, and is suitable for a variety of applications. The converters come with a variety of features, such as input rectification, EMI filter, inrush current limiting, DC output voltage regulation, isolation transformer, output voltage monitoring, and a control circuit. With these features, the converters are suitable for a variety of applications, such as industrial power supplies, automotive applications, and backup systems.
