DC DC Converters-SQM48T20010-PDAP application field and working principle

DC DC converters are essential components in electronic devices as they facilitate the conversion of power from one DC voltage to another. The SQM48T20010-PDAP converter is a particular DC DC converter that provides a variety of features and is widely used in a variety of industries. This article provides an overview of its application field and working principle.

Application Field

The SQM48T20010-PDAP converter is a high-efficiency, high-voltage isolated DC/DC module mainly used in industrial control systems, power monitoring systems, electric vehicle systems, electric bicycle systems, green energy, electric toys, and other circuit isolations. It is also suitable for voltage converters in various high-voltage devices and power systems, and for use in inverter, UPS, frequency converter, ESB, etc.

The remarkable features of the converter make it an ideal choice for high-end application fields. It works with excellent heat dissipation due to the built-in air gap. This air gap allows for lower temperature rise and greater efficiency. Moreover, the unique Sine-wave PWM technology guarantees high efficiency along with a high switching frequency of 48 kHz. It has wide input voltage range with a wide temperature operational range of -40 to +85 ℃, making it suitable for almost any application.

Working Principle

The SQM48T20010-PDAP converter works on a voltage transformation principle and works on the principle of pulse width modulation (PWM). It converts the input voltage to the desired output voltage in a frequency-hedge pulse width modulation form.

The operating principle of the converter is quite simple and efficient. The incoming power enters the converter through the input transformer and is then rectified to the DC power form. The DC power is then fed to the oscillator circuit, which produces a digital square wave signal with a fixed frequency. The filter circuit then converts the signal into a sine wave signal for PWM processing. The PWM signal is fed to a switching circuit to produce power and helps in controlling the switching of the transistor, thus producing the desired output voltage.

The output of the converter is regulated due to the efficient yet simple control technology used. This technology helps to reduce input current ripples and output fluctuations while providing excellent braking effect and over-voltage protection.

Conclusion

The SQM48T20010-PDAP converter is a high-efficiency, high-voltage isolated DC/DC module with a wide input voltage range and high switching frequency, making it suitable for various high-end application fields. It has an efficient yet simple operating principle based on the PWM technology and its output is regulated with extremely low current ripples and output fluctuations. Thus, the SQM48T20010-PDAP converter has made it into several industries and applications as an ideal choice.
