IGBT DRIVER (MTC-3073)

IGBT DRIVER (MTC-3073)
Prominent Data
Driver for double IGBTs of mid-range, in a 1200-1700V working
range. This driver by itself can control a branch (TOP and BOTTOM)
This card, unlike another type of Driver is personalized from factory.
Does not need additional elements such as printed circuits, resistors,
capacitors, neither calculations, nor adjustments, just input control
signals and the IGBT connections. (collector, emitter and gate).
Each Driver is adjusted to be able to operate only with one or two
IGBT modules. With this personalization a better performance is
obtained and there is a better adaptation to electric and physical
characteristics of each IGBT.
Easy connections from the board to the IGBT through faston
terminals. Connections with interface through double 16PIN row.

Characteristics
4500V (Up.eff.) electric insulation between primary and secondary.
4500V (Up.eff.) electric insulation between secondaries.
Inputs TOP, BOTTOM and INH (inputs CMOS 20V max., 3K3 impedance).
Inputs signals filtration. Signals with less time than 1µs are rejected.
Trigger inputs protected against electrostatic discharges.
Min. dead time generation, can not be accumulated to the one applied by software.
Working cycle from 0 to 100%.
Recommended tension for boards supply 16 VDC.
Protection against supply drop in voltage in both secondaries +13V/-13V.
Protections against overcurrents by comparison of the Vce.sat. with prefixed standard.
Soft shut down of the IGBT with alarm. (This procedure avoids Vce overtension in the most
unfavourable moment).
Overcurrent active protection on the switching off of the IGBT “DVRC” (Dynamic Voltage
Rise Control). This protections acts from 900V on. Configurated according to model.
Open-Collector output alarm. Alarm prolonged during 30ms.
Signals and supply connexion through double pins row.
Working temperature from –40ºC to 70ºC
Commutation frequency 20 KHz
Possibility of higher frequencies up to 60 Khz for other IGBTs families.
Measurements 67x116mm.
Trigger with +15V/-15V in both IGBTs
Easy adaptation with interface MTC-3074.
