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 […]
SEPIC Converter based on MT3608 is open source
https://www.electronics-lab.com/sepic-converter-based-on-mt3608-is-open-source/
DC-DC converters are needed in almost every commercial product, whether it is industrial, medical, defensive, automotive, or any other application. These converters are electronic circuits that can convert the DC voltage from one level to another. There are two types of DC-DC converters: linear and switching converters. Linear converters are resistive which means that they […]

SEPIC/Ćuk converter sprouts second output
https://www.electronics-lab.com/sepiccuk-converter-sprouts-second-output/
by Gheorghe Plasoianu @ edn.com Many applications require positive and negative supply voltages, with only one voltage requiring tight regulation. This Design Idea describes a dual-output, hybrid SEPIC–Ćuk converter whose positive output voltage can be lesser or greater than the input voltage. The unregulated negative output is a mirrored replica of the positive output. SEPIC/Ćuk […]
