Infineon Applied sciences new analysis platform includes of a motherboard with interchangeable drive playing cards
The playing cards function driver ICs for high-frequency switching of SiC energy gadgets
Double pulse testing is an ordinary process for designers to study in regards to the switching behaviour of energy gadgets. To facilitate the testing of drive choices for the 1200 V CoolSiC MOSFET in TO247 Three-pin and Four-pin packages, Infineon Applied sciences has launched a modular analysis platform. It includes of a motherboard with interchangeable drive playing cards. The drive choices embody a Miller clamp and a bipolar provide card. This improvement will assist enhance the large utilization of silicon carbide and shorten the time-to-market for a wide range of purposes.
Intensive motherboard efficiency
The motherboard of the analysis platform is cut up into two sections: the first provide aspect having the 12 V provide and the pulse-width modulation (PWM) linked whereas the secondary aspect has the secondary provide of the motive force, the half-bridge with connections for the shunt for present measurement and the exterior inductance. The constructive working voltage of the drivers could be adjusted between +7.5 V and +20 V, whereas the unfavorable voltage could be regulated between +1 V and -Four.5 V. The motherboard was designed for a most voltage of 800 V and a most pulse present of 130 A. For measurements at excessive temperatures of as much as 175 diploma Celsius, the heatsink can be utilized along with a heating ingredient.
Appropriate reference design
Serving as a reference design for 2 drive choices, the playing cards function driver ICs from the EiceDRIVER household for high-frequency switching of SiC energy gadgets. The primary modular card comprises the 1EDC Compact 1EDC20I12MH with an built-in lively Miller clamp, which is often activated under 2 V. The second drive card contains the 1EDC Compact 1EDC60H12AH permitting a bipolar provide, the place VCC2 is +15 V and GND2 is unfavorable. With these two driver playing cards, the portfolio affords massive choices most popular by designers for driving SiC MOSFETs.
All three elements of the modular analysis platform – motherboard, Miller clamp and bipolar drive playing cards – could be ordered now. A further drive card for brief circuit detection will probably be added to the portfolio throughout summer time 2020 and a card for SMD bundle testing will observe through the second half of this yr.
