Switchmode Power Supply Topologies Explained
https://www.electronics-lab.com/switchmode-power-supply-topologies-explained/
The role of power supply is crucial for electronic circuits because without sufficient power, the circuit cannot function at its optimal level. On the other hand, an exceeded power supply can deteriorate the circuit components by heating effect. There are usually two choices for power supply topologies; Linear Power Supply and Switched Mode Power Supply […]
