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 ...

Front end topology and some tips to design a mixed bridge circuit that effectively protects the design from an overvoltage. A robust solution using a new SCR generation and front end topologies that ...

Powering LEDs from a wide dc range—say, 30 to 380V—without wasting a lot of power in the regulating block, is a difficult task when the LED current needs to be constant. Dedicated LED drivers are ...
