International Rectifier Corp. (IR, El Segundo, CA) introduced a new family of 1,200V, short-circuit-rated, motor drive modules with six IGBTs, each with a built-in, free-wheeling diode. The new modules expand the IR line of inverter modules used in variable speed motor drives for plastics forming machines, packaging equipment, printing presses and other industrial applications up to 15kW.
The new devices are housed in the ECONO2 package. Two configurations are available: a three-phase inverter and a power-integrated module, which combines a three-phase bridge, a brake and a three-phase inverter. Both module types include a negative temperature coefficient thermistor.
The new inverter module family is composed of three SixPack™ GB25XF120K, B35XF120K and GB50XF120K fully insulated inverter modules based on IR's non-punch-through IGBTs. The IGBTs feature a square reverse-bias safe operating area, and withstand 10µs short circuits. A low and positive temperature coefficient improves ruggedness during startup and prevents abnormal current and voltage spikes.
The new variable speed inverter modules are available immediately. Pricing begins at $80.04 each for the GB15RF120K in 100-unit quantities.
