“…External current sensors or two-chip solutions (GaN and Si) are also often used and investigated for GaN power electronics [ 47 , 48 , 49 , 50 , 51 , 52 , 53 , 54 , 55 , 56 , 57 ]. State-of-the-art low-voltage GaN motor inverters today still use at least three half-bridge ICs and three sense resistors [ 3 , 58 , 59 ]. In silicon (Si), monolithic three-phase motor drive ICs with integrated current sensing and other functionality have been available for decades, for example, using a lateral insulated gate bipolar transistor (LIGBT) power IC technology [ 60 ].…”
