The emergence of fast switching WBG devices has dramatically enhanced power density in a range of power conversion circuits such as active rectifiers, LLC bridges, Phase shifted full bridges, Dual active bridges to name a few. These circuits form the backbone of efficient AC-DC and DCDC stages in battery chargers for EVs, forklifts, solar inverters and power supplies, especially where power density is key. The fast switching enabled by these devices is best exploited in advanced packages such as TO247-4L, D2PAK-7L which have a Kelvin Gate Return. However, there are often supply-chain reasons why users are constrained to use standard packages like TO247-3L, TO220-3L and D2PAK-3L, which has high levels of common source inductance.
