PS11012

Overview

The PS11012 is a flat-base insulated integrated power module by Mitsubishi Semiconductor, combining a 3-phase AC-to-DC converter bridge, dynamic braking circuit, and a 3-phase IGBT inverter. It utilizes third-generation IGBT technology for an output current capability of 1.5A (rms) at 100% load and 2.25A (rms) for 1 minute at 150% overload. The device integrates drive circuits, high-voltage level shifting, short-circuit protection, under/over-voltage protection, and over-temperature protection within a single package.

Feature Summary

• Integrates a 3-phase rectifier, brake circuit, and IGBT inverter with dedicated drive and protection logic.
• Provides high-speed isolated level shifting and short-circuit protection for upper and lower leg IGBTs.
• Features open-collector fault outputs for short-circuit, supply abnormality, and over-temperature conditions.
• Includes analogue signal feedback to reproduce actual inverter output phase currents.

Applications

• Acoustic noise-less 0.2kW/AC200V class 3-phase inverters
• General motor control applications

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 FO signal.

What is the function of the CL pin?

The CL pin provides a current limit warning signal when the arm current exceeds the defined limit, operating on a pulse-by-pulse scheme.

Can the module be directly coupled to a CPU?

Yes, due to the integrated HVIC, direct coupling to a CPU without opto or transformer isolation is possible using the 5V CMOS/TTL compatible inputs.
