• Power supplies for medical and communication applications
• DC motors and generators

AEH20F24 Working Principle

The AEH20F24 operates on the principle of pulse-width modulation (PWM) in order to convert the input voltage to the output voltage. In PWM, the output voltage is controlled by changing the ratio of the "on" and "off" time in each period of the switching cycle. The AEH20F24 incorporates a PWM controller and a MOSFET power switch to perform this switching.

The PWM controller is responsible for adjusting the duty cycle, or the ratio of "on" and "off" time periods. A closed loop with feedback from the output monitors the output voltage and adjusts the duty cycle according to the difference between the commanded and measured output voltages, resulting in a constant output voltage.

The MOSFET power switch is responsible for switching the input voltage to the output. The switching frequency is adjusted by the PWM controller and can be set to as high as 500kHz. This high frequency allows for smaller size and lighter weight components due to reduced power losses from the switching.

The AEH20F24 also incorporates a wide range of protections, such as over-current and over-temperature protection, to ensure the converter is safe to use. The converter can also be triggered remotely via an external signal.

Conclusion

The AEH20F24 DC DC converter is a versatile and cost effective solution for a wide range of industrial and consumer applications. Its sophisticated design takes advantage of pulse-width modulation and remote triggering to provide reliable, efficient, and accurate voltage conversion.
