Coreless transformer gate driver

• Coreless Transformers or Coreless Planar Transformers (CPT) were first developed as a solution for insulating the high voltage power circuit from the low voltage control circuit allowing integration on-chip. • The coreless transformer technology has been chosen by main major driver IC manufacturers as the most adequate.  · Unlike opto-isolator gate drivers, coreless transformer gate drivers exhibit a relatively flat turn on and turn off times over temperature. Opto-isolator gate drivers tend, on the other hand, to change behavior substantially with temperature variations with a much longer difference between turn on and turn off times, which equates to reduced efficiency due to larger dead www.doorway.ruted Reading Time: 8 mins. Gate driver ICs serve as the interface between control signals (digital or analog controllers) and power switches (IGBTs, MOSFETs, SiC MOSFETs, and GaN HEMTs). The integrated gate-driver solutions reduce your design complexity, development time, bill of materials (BOM), and board space while improving reliability over discretely-implementedAuthor: Infineon.

EiceDRIVER™ isolated gate driver family use the state-of-the-art coreless transformer (CT) isolation technology The CT based isolated gate driver offers higher current, lower power consumption, better CMTI and best in class propagation delay matching. operating limitations related to the saturation of the core. By an isolator element into the gate driver, utilizing for example the Infineon’s Coreless Transformer (CT) technology as shown in Figure 2, it is possible to produce functional and reinforced isolated gate driver ICs. The EiceDRIVER™ 2EDi product family [4] is one example of.

At low operating frequency, the magnetizing inductance has such low impedance that the driving power requirement could become excessive. This paper describes. These coreless transformers are used for transmitting switching information between input chip and output chip. Two isolated chips ensure galvanic isolation.
