PS12012-A

Overview

The PS12012-A is a flat-base insulated Application Specific Intelligent Power Module (ASIPM) manufactured by Mitsubishi Semiconductor. It integrates a 3-phase IGBT inverter bridge with dynamic braking capabilities, utilizing third-generation IGBT and diode technologies. The module supports an AC 400V class line output and provides integrated drive, protection, and system control functions for P-side, N-side, and brake circuit IGBTs. Key electrical ratings include a supply voltage of up to 600V, continuous inverter output current of 1.2A RMS at 100% load, and 1.8A RMS at 150% overload for one minute. Thermal resistance from junction to case is typically 3.0°C/W for the inverter IGBT.

FAQ

How does the module handle arm shoot-through?

The module includes an input interlock protection circuit that cuts off both upper and lower IGBTs of a mal-triggered phase if simultaneous LOW level signals are detected, outputting an FO1 fault signal.

What is the recommended boot-strap charging procedure?

Apply a train of short ON pulses at all N-IGBT input pins for adequate charging, with a pulse width of approximately 20 μs and 10 to 500 pulses depending on capacitor size.

Can the module be directly coupled to a CPU?

Yes, due to the integrated photo-coupler inside the module, direct coupling to a CPU is possible without any external opto or transformer isolation.
