AC DC Converters

ECM100UQ44 Application Field and Working Principle

AC DC converters are widely used in various fields because of their reliable, cost-effective and high efficiency capabilities. ECM100UQ44 is one of the AC DC converters that belongs to S308 family and has 100W output and the typical efficiency of 94%~95.5%. It is suitable for applications such as industrial and electrical power control, communication, medical, consumer, and automotive. Specifically, ECM100UQ44 is one of the most popular AC DC converters used in solar energy field.The ECM100UQ44 conforms to international safety regulations for the design of electrical power supply, such as RoHS, IEC60950-1, UL/cUL, CB, etc. It supports wide DC input voltage range (4.5V-14V) and wide AC input voltage range (80-265VAC). It is also equipped with the feature of short circuit protection which prevents output short circuit in the circuit caused by wrong operations.The working principle of ECM100UQ44 is simple and remarkable. It converts AC input to DC output by rectifying waveform from an AC source and then regulating to an appropriate voltage. This is achieved by a diode rectifier bridge. The rectified voltage is then sent to a voltage regulator for regulating to the desired output voltage. During the operation, this voltage regulator works to maintain a fixed voltage with respect to a reference voltage. Finally, the regulated output voltage is filtered by a capacitor or inductor filter in order to reduce the ripple of the DC output. The whole process is usually done by a circuit board with components such as transistors, resistors, capacitors, and inductors. In addition, the ECM100UQ44 also has high efficiency due to low output ripple and low no load consumption. It also has two output voltage points (12V/24V) that can be easily adjusted without using any additional resistors.In conclusion, ECM100UQ44 is one of the most widely used AC DC converters in solar energy field due to its simple process of converting AC to DC power, wide input and output voltage range, and high efficiency. Its features make it an ideal choice for various applications such as industrial and electrical power control, communications, medical, consumer, and automotive.
