The design is not qualified in terms of safety requirements, manufacturing and operation over the entire operating temperature range or lifetime.
EVAL-FFXMR20KM1HDR Evaluation board description and getting started guide Safety precautions Safety precautions Please note the following warnings regarding the hazards associated with development systems. Table 1 Safety precautions Warning: The DC link potential of this board is up to 1500 VDC. When measuring voltage waveforms by oscilloscope, high voltage differential probes must be used.
Due to the usage of the EiceDRIVER™ 1ED38x0Mc12M and its flexible parameter setting options via I2C-BUS the EVAL-FFXMR20KM1HDR can be quickly adapted to different applications (like DC/DC-converter, Solar applications, UPS systems, Solid state transformer, Drives and others) without changing the hardware.
The board appears as shown in Figure 1. For a complete testing of the board some components must be ordered in addition as shown in Figure 2. The Infineon EVAL-1ED38X0DCT microcontroller board ideally be used in order to be able to configure all the parameters in an easy and fast manner. On the power side, any 62mm 2kV half bridge module can be used for evaluation purpose.
The evaluation board at a glance Main features The EVAL-FFXMR20KM1HDR is an evaluation board for the EiceDRIVER™ 1ED38x0Mc12M gate drivers ICs to be used together with our 62 mm 2 kV half-bridge module with CoolSiC™ MOSFET. The board is designed for easy measurement and configuration of the gate driver and module parameters.
The EVAL-FFXMR20KM1HDR operates with a supply voltage of up to 24 V. It generates an output voltage of up to 18 V at the gate terminals, depending on the load conditions. To switch the device, a pulse width modulation (PWM) for both, the top and the bottom side need to be applied at the connector input.
′ Equation to calculate Vneg for the negative gate voltage adjustments Figure 6 The EVAL-FFXMR20KM1HDR is equipped with the EiceDRIVER™ Enhanced single-channel isolated gate driver 1ED3890MC12M. The 1ED3890MC12M belongs to the EiceDRIVER™ Enhanced 1ED38xx family (X3 digital family) and has a I C bus for parameter adjustment.
2.2.3 Evaluation of the EVAL-FFXMR20KM1HDR with another microcontroller While not recommended to new users or for fast evaluation, the EVAL-FFXMR20KM1HDR can be used with any microcontroller capable of communicating over I C and generating PWM signals. For this, it is important to read the documentation, especially the reference manual, of the gate drivers.
