Gate drivers — the critical link in power-device performance: part 3

June 11, 2025 By Bill Schweber

This section will discuss some of the many subtleties of the gate driver and its power source. Other gate-driver converter considerations Gate-driver dc-dc converters have other unique issues. Among them are: 1) Regulation: the load on the dc-dc converter is close to zero when the device is not switching. However, most conventional converters require a […]

Gate drivers — the critical link in power-device performance: part 2

June 4, 2025 By Bill Schweber

Thus far, we have examined the general issue of power devices and their characteristics. This part goes into the details of the power-device gate driver. Gate-drive details To drive current into the gate, the positive rail’s voltage should be high enough to ensure full saturation/enhancement of the power switch, but without exceeding the absolute maximum […]
