Readily available positive-voltage controllers can be configured for hot-swapping either dual positive and negative supplies, or a single negative supply. Jim Sherwin, Senior Member of the Technical ...

This reference design presents an automotive VFD power-supply controller used as a boost circuit that will maintain a constant voltage in the event when the battery is affected by cold temperatures.

A typical low-voltage variable-frequency drive. Industrial facilities commonly use variable-frequency drives (VFDs) to control the speed at which alternating current motors operate. Let’s examine a ...

Part 2: A 60V buck-boost controller drives high power LEDs, charges batteries and regulates voltage with up to 98.5% efficiency at 100W and higher. Part 3: Offline LED lighting simplified: A high ...
