Energize a Circuit An Innovative Switched-Mode Power Supply Design

摘要

Energy control is an essential aspect of many electronic applications. If you build a switched-mode power supply (SMPS), you can regulate a design's current to meet your specific project goals. Most engineers, technicians, and designers needrnpower supplies for energizing their circuits. Do you? You can use a power supply instead of batteries. If portability is not a requirement, a power supply is a viable alternative to batteries because it costs less to use. It's nice if you can adjust the voltage, but it is even better if you can also modify the current. The switched-mode power supply (SMPS) I recently designed enables you to adjust the voltage from 0 to 20 V and the current from 0 to 1 A (see Photo 1). You can change the voltage and current by entering the value on the keypad and checking the output on the 2×16 LCD module.
