IGBT and SLLIMM IPM Slide 12

This slide shows the 600 volt ‘V’ series IGBT family. All of these devices are in full release. For each respective current range there are three options with respect to freewheeling diode. As can be seen, the operating frequency for these devices ranges from 20 – 120 kHz. If the device has a F suffix, without a preceding D, it denotes that there is no diode co-packaged with the IGBT. This type of device will usually target boost PFC topology or other boost converters where no freewheeling diode is needed, or it may target other topologies like the three-level NPC where some IGBTs may benefit from having an external SiC rectifier in parallel with them. If the device has a DF suffix, a very fast recovery rectifier is included as the freewheeling diode. This option targets hard switched, very high frequency converter applications such as UPS, photovoltaic inverters, welding inverters, pro-audio class D amplifiers, and PFC. A device with a DLF suffix has an included low forward voltage drop (Vf) soft recovery diode. This option targets soft switched and resonant topologies as employed in induction heating and cooking, microwave oven inverters, and other resonant converter applications.
