AC DC Converters – PSDR030W Application Field and Working Principle

AC DC converters provide the ability to convert AC voltage to DC voltage at different outputs and output power levels. PSDR030W is a hybrid AC/DC converter featuring a smaller footprint than traditional converters. It can deliver a steady output from an input variability of 85 to 264 volts AC or 127 to 300 volts DC.

The PSDR030W is an efficient and reliable AC/DC converter rated for output powers from 30 Watts to 120 Watts. Its very low profile design (2.3 x 1.6 x 1.1 in), as well as its universal input voltage range of 85 to 265 volts AC or 127 to 300 volts DC makes it a suitable choice for applications with very limited space or operating environments combining both AC and DC sources.

The Operating Principle of the PSDR030W is fairly simple thanks to its high frequency switching technology, which allows for the conversion of AC to DC at very fast response times. The input voltage is rectified and fed to a storage capacitor. The high frequency switching regulator then converts the stored DC voltage to a stable output voltage. The switch or transistor is operated at very high frequency and driven with a pulse width modulation signal that is created by the internal control IC.

The high frequency switch, or transistor, is operated in a linear mode allowing for optimized efficiency and high conversion accuracy. The device driver, IC, constantly monitors the output voltage and continuously adapts the width of the pulses fluctuating the pulse width enough to regulate the output which results in a stable output voltage despite of input voltage variations. The low cooling requirements of the PSDR030W make it desirable in applications which need small power at very constrained spaces.

Typical applications of PSDR030W can be found in industrial, embedded systems, telecom, transportation and appliance industries. Its feature set makes it ideal for indoor and outdoor applications in harsh environments with limited space, high efficiency and high reliability requirements.

The versatile feature set and performance makes the PSDR030W a dependable choice for a variety of AC/DC conversion applications. Its hybrid design is versatile enough to allow input operation from both AC and DC voltage sources. Its reliable performance and a low profile design translates to the capacity to deliver output from 30 Watts to 120 Watts in a fraction of the space needed by conventional converters.
