PS11015

Overview

The PS11015 is a flat-base insulated type integrated power module manufactured by Mitsubishi Semiconductor. It functions as an Application Specific Intelligent Power Module (ASIPM) containing a three-phase AC-to-DC converter bridge and a three-phase IGBT inverter bridge utilizing third-generation IGBT and diode technology. The module integrates dynamic braking circuits, drive logic, and protection mechanisms. Rated for 600V blocking voltage, it supports an inverter output current of 7.0A RMS at 100% load and 10.5A RMS for one minute under 150% overload conditions.

Feature Summary

• Integrates a three-phase rectifier bridge with a three-phase IGBT inverter bridge and a dedicated dynamic braking circuit.
• Includes high-voltage isolated level shifting, short-circuit protection, and under/over-voltage protection for the control supply.
• Provides system over-temperature protection and fault signaling via open-collector outputs.
• Features analogue signal feedback to reproduce actual inverter output phase currents.

Applications

• Acoustic noise-less 1.5kW class 3-phase inverters
• AC200V class motor control applications

Procurement Notes

Verify that the component is sourced from authorized distributors or Mitsubishi Semiconductor directly. Confirm the part number matches the specific flat-base insulated type designation. Ensure compatibility with the required 15V control supply voltages and check for any ordering suffixes that may indicate specific thermal or packaging variations.

Selection Notes

Select this module for applications requiring a compact solution combining rectification, inversion, and intelligent control. Ensure the cooling system can maintain the case temperature within the -20°C to +100°C operating range. Verify that the input PWM signals are compatible with the specified 5V CMOS/TTL interface levels and that the isolation voltage requirements are met.

Part Context

This component belongs to the ASIPM family designed to simplify the design of three-phase motor drives. By integrating the power stage with gate drivers and protection circuits, it reduces the component count and board space required compared to discrete solutions. The flat-base construction facilitates efficient heat dissipation through direct mounting to a heatsink.

Replacement Considerations

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 phase if simultaneous low-level inputs are detected, outputting an FO signal.

What is the recommended control supply voltage?

The recommended control supply voltage (VDH/VDB) is 15V, with an allowable range of 13.5V to 16.5V.

Can the short-circuit protection be used for load regulation?

No, the short-circuit protection is intended primarily to protect against catastrophic faults and should not be used for system load current regulation or overload control.
