Design Considerations To Consider When Selecting A Half-bridge Gate Driver

When designing power electronics circuits that utilize half-bridge gate drivers, there are many factors that need to be considered. Some of those factors include power level, power density, operating frequency and converter operation such as unidirectional and bidirectional. These factors are discussed with regards to the associated half-bridge gate driver in relation to the applications where used.

Many challenges are associated with designing DC-DC converters with high power and output current levels. The following application note highlights and explains those challenges in the context of half-bridge gate drivers.
