The EiceDRIVER™ 2EDi is a family of fast dual-channel isolated MOSFET gate-driver ICs providing functional(2EDFx) or reinforced (2EDSx) input-to-output isolation by means of coreless transformer (CT) technology. Dueto high driving current, excellent common-mode rejection and fast signal propagation, 2EDi is particularly wellsuited for driving medium- to h大闸蟹怎么吃
igh-voltage MOSFETs (CoolMOS™, OptiMOS™, CoolSIC™) in fast-switching power systems.
The gate drivers of the EiceDRIVER™ 2EDi product family are designed for fast-switching, medium to high powersystems with MOSFET switches. They are optimized for high timing accuracy over temperature and productionspread. The reliable accurate timing simplifies system design and provides better power conversion efficiency.
The 2EDSx, 2EDFx dual-channel reinforced (safe) and functional isolated product variants are available withdifferent drive strengths: 4 A/8 A for low-ohmic power MOSFETs, 1 A/2 A for higher Ron MOSFETs or slowerswitching transients (EMI). The 1 A/2 A reinforced isolation driver can also be ud as a PWM Data Coupler incombination with a non-isolated boost gate driver such as 1EDNx 4 A/8 A placed in clost proximity to theSuperjunction power switches.
Two independent and galvanically isolated gate driver channels ensure that all 2EDi versions can be ud in anypossible configuration of low- and high-side switches.
Improved system robustness is supported by min. 150 V/ns Common Mode Transient Immunity (CMTI), PWMinputs with 18 ns noi filter, UVLO on output side including a safety lf-lock-down of driver outputs in ca ofinput UVLO (VDDI < 3 V), PWM outputs with up to 5 A peak rever current capability and an intrinsically robustgate driver design.

评估板EVAL_3K3W_TP_PFC_SIC
The EVAL_3K3W_TP_PFC_SIC board is a system solution enabled by Infineon Technologies power miconductors as well as drivers and microcontroller. The evaluatio
n board consists of a bridgeless totem-pole topology and it is intended for high-end applications in which the highest efficiency is required. Furthermore, the totem-pole topology is simple and offers a reduced part count and full utilization of the PFC inductor and switches [1]. For the reasons, totem-pole PFC enables high power density at a limited system cost for high-performance systems. In addition, the EVAL_3K3W_TP_PFC_SIC board provides rever power flow (inverter operation for grid-connected applications) due to the inherent bi-directional power flow capability of the totem-pole topology.
The totem-pole topology in PFC applications with CCM operation is feasible by using wide band-gap miconductors [1]. In this ca, the Infineon CoolSiC™ MOSFET in TO-247 four-pin package is ud to push the efficiency to 99 percent at half-load (Figure 2). The converter operates exclusively at high-line (176 Vrms minimum, 230 Vrms nominal) in CCM with 65 kHz switching frequency.
The PFC function to achieve bulk voltage regulation while demanding high-quality current from the grid is implemented with an Infineon XMC1404 microcontroller [2]. Further detail on PFC control implementation in the XMC™ 1000 family can be found in the application notes of other Infineon PSU and PFC evaluation boards with classic boost or dual boost topologies [3][4][5].
The 3300 W bridgeless bi-directional (PFC/AC-DC and inverter/AC-DC) totem-pole prented in this application note is a system solution developed with Infineon power miconductors as well as Infineon drivers and controllers. The Infineon devices ud in the implementation of the EVAL_3K3W_TP_PFC_SIC board are listed below.

A simplified block diagram of the bridgeless topology with the mentioned devices from the Infineon portfolio is shown in Figure 3. The diode bridge in front of the totem-pole PFC converter is meant to be a current path for start-up or surge conditions and it is not part of the current path during the steady-state converter operation. The power flow direction, which will lect the converter operation – forward power flow or PFC operation versus rever power flow or inverter operation – can be lected by a switch connected to the XMC™ microcontroller as a digital input pin.
