Semikron has demonstrated the versatility and scalability of its SEMiX family of IGBT half-bridge modules with the introduction of the SEMiX4.
Product catalogue weighs in at 2kg
Following research in the industry into users' preferred methods of sourcing product data, Semikron has published a new edition of its product manual - on paper.
The unit features thermal resistance of 0.95K/W and at junction temperature of +175C.
Power, control and auxiliary contacts are connected directly to the printed circuit board via springs, not solder joints.
This results in a higher quality of assembly.
Cost-efficient assembly of the module, printed circuit board and heat sink is achieved with simple snap-on mounting with one standard screw.
Handling is reduced and the parts count is lower than with discrete designs.
A high-voltage driver IC with advanced level-shifter technology is integrated into the 600V convertor-inverter-brake and 1200V inverter (six-pack) modules, providing IGBT driving without an optocoupler.
The SOI technology provides complete latch-up immunity, since all switches are di-electrically insulated.
A level shifter for each channel allows the presence of negative secondary offset voltages.
The integrated gate driver remains fully operational for any applied offset voltage down to -50V, providing flexibility in the design of a power system.
The gate driver IC features overcurrent shutdown circuit protection by using an external shunt resistor in the ground plan as well as an under-voltage lockout for all channels and fault signalling.
A shut-down can also be forced by the system controller, using the shutdown input.
Logic interlock protection is included to ensure that simultaneous conduction of the IGBTs in a phase leg cannot occur.
The MiniSKiiP IPM is suitable for industrial and consumer drives up to 15kW as well as process control and solar applications.
Using Trench-Field-Stop IGBTs, the IPMs are available in 600 and 1200V versions and have been designed for nominal current ratings of up to 72A.
