Power Semiconductor Gate Drivers are designed to drive IGBTs and MOSFETs. For IGBTs, the Gate Driver makes VCE fault protection both compact and affordable. They can provide electrical isolation between the TTL compatible inputs and output drive circuitry by use of an internal optocoupler circuit. Some models are built with integrated short circuit protection and many models include a built-in, isolated DC-DC converter. Enhanced features can include integrated VCE detection, under-voltage lockout (UVLO), soft IGBT turn-off, isolated open collector fault feedback, and Miller clamping. The typical SIP package outline for a Gate Driver takes up as little board space as possible, minimizing the total board space required and leaving more mounting space available for other circuitry on the PCB.
Applications for Gate Drivers include all of the typical applications for IGBTs and/or MOSFETs, including Traction Drive systems, Wind Power Inverters, Solar Power Inverters, Three-Level Inverters (TLI), Industrial Drives, Welding, and UPS. Richardson RFPD / Arrow RF & Power carries Gate Drivers capable of driving medium and high-power IGBTs with reverse voltages specified from 600V to 6500V.
Attributes which are important in selecting the right Gate Driver for your application include: Usable Device Range (V, A); Output Current (A); Short-circuit Protection (yes/no); Integral DC-DC Converter (yes/no); and Package Type.
Our website includes a robust selection of Gate Drivers from CT-Concept, Microsemi, Powerex, and Semikron. Custom solutions are also available from Richardson RFPD
The parametric search filter allows the user to quickly find the parts they need by filtering the results in real-time.
Additionally, some attributes allow for the conversion of their base type to different types. For example, the attribute group for minimum frequency is shown in MHz. The values can be converted to be shown in KHz or GHz by selecting the conversion type from the ‘Select Conversion’ drop down list.
Any Attribute that does not interest the user can be hidden by clicking on the ‘X” in the upper-right corner of the attribute. To show any hidden attributes, simply click the ‘Unhide Attributes’ button in the bottom of the parametric search filter.
If you are experiencing performance issues, please use a newer browser such as Chrome or Firefox, or disable the ability of the filter to perform dynamic updates by deselecting the checkbox titled ‘Allow Filters to Dynamically Update Parametric Search Attributes’.
