AC DC Converters

AA30T051515D is a high frequency, high efficient AC-DC converters. It allows DC voltage input and accepts AC voltage variation from 100v to 240v. It also features input line under-voltage protection and over-current protection.

Application Field

AA30T051515D AC-DC converters are applicable for communication system, industrial equipment, power system, medical equipment, and test and measurement equipment, etc. It can also be used in other power conversion process such as DC-DC or AC-AC.

Working Principle

AA30T051515D AC-DC converters operate on the switching power supply principles. This type of power supply features high frequency switching with low AC input voltage, and provides high power conversion efficiency. As an AC-DC converter, AA30T051515D consists of a full-bridge diode rectifier with four active switches, an AC-regulatable transformer, a capacitance filter, and a Power Factor Correction (PFC) controller. The full bridge rectifier converts the input voltage into direct current, which is then filtered by the capacitor. The output voltage is regulated by using the AC-regulated transformer and by adjusting the on/off times the PFC controller shortens the output voltage pulsations.

The transformer is the most vital component in this AC-DC converter, since it actually varies the input voltage and keeps the output voltage unregulated. The transformers are designed to reduce the impedance of the load, so it can be used in various loads. The PFC controller is necessary, as it helps to reduce the waste of power in the system as it reduces the output voltage pulsations, resulting in a much lower THD in the system.

Conclusion

AA30T051515D AC-DC converter can be used in various applications, from communication device, power system, to medical equipment. Its full-bridge diode rectifier, AC-regulatable transformer, capacitance filter, and PFC controller work together to maintain the accuracy of the power output. Such a reliable converter not only provides more efficient in power usage, but also ensures a much safer output.
