Introduction to AC DC Converters

AC DC converters are electrical circuits used to convert alternating current (AC) to direct current (DC). This type of electrical device is necessary when a design requires DC power for operation, but only AC power is available. AC DC converters provide a means of changing the voltage of alternating current, as well as providing a steady direct current from a variable AC input.

The AA15D1212C application field and working principle

The AA15D1212C is a type of AC DC converter specifically designed to deliver reliable, accurate DC power from a variable AC input. The AA15D1212C uses a high frequency, soft switching topology to provide high efficiency levels and tight voltage regulation. This AC DC converter can deliver up to 150W of regulated DC power from a 85-264Vac input, and features a frequency range of 47-63Hz. The AA15D1212C has a peak efficiency of 97.5%, low no-load power, and can provide up to 12A of load current.

The working principle of the AA15D1212C is to convert the AC input voltage to an intermediate DC voltage and then convert this voltage to the desired DC output voltage. This is accomplished by a switch mode power conversion process, which involves switching the input voltage on and off at a high frequency. This high frequency switching reduces the size of the components necessary for the power conversion process, enabling the use of smaller, more cost effective circuits. The switch mode power conversion process also increases the efficiency of the power conversion process, reducing energy losses and increasing efficiency.

The AA15D1212C AC DC converter also features a range of safety features including overload protection, short circuit protection, and over temperature protection. The overload protection feature ensures that the output current will be automatically limited if the maximum output current is exceeded. The short circuit protection feature limits the instantaneous output current to a safe value to protect both the converter and the load. The over temperature protection feature limits the output power and shuts down the current if the converter reaches a pre-set temperature.

Conclusion

The AA15D1212C is a high efficiency AC DC converter designed to deliver reliable, accurate DC power from a variable AC input. This AC DC converter uses a high-frequency, soft switching topology to provide high efficiency levels and tight voltage regulation. It features a range of safety features including overload protection, short circuit protection, and over temperature protection. The AA15D1212C also has a peak efficiency of 97.5%, low no-load power, and can provide up to 12A of load current.
