PS12034

Overview

The Powerex PS12034 is an Application Specific Intelligent Power Module (ASIPM) from the Intellimod series, rated for 1200 Volts and 10 Amperes. It integrates a three-phase IGBT inverter bridge with a rectifier bridge for AC-to-DC conversion. The module includes integrated High Voltage Integrated Circuits (HVICs) providing gate drive, protection, and system control functions. Key electrical parameters include a collector-emitter saturation voltage of 3.6V at 10A, switching times up to 4.0µs, and a recommended DC-link supply voltage of 600V to 800V. It features built-in over-current, short-circuit, and under-voltage protection with fault output signaling.

Procurement Notes

Verify the specific part number PS12034 against official Powerex documentation to confirm current availability status, as component lifecycles may change. Ensure that the mounting torque specifications and thermal interface requirements are strictly followed during installation to maintain device integrity and performance ratings.

Selection Notes

Select this module for small inverter applications operating up to 20kHz where space efficiency and reduced design time are priorities. Consider the 1200V rating and 10A continuous current capacity when sizing for load requirements. Verify compatibility with the required control signal levels and ensure adequate heat sinking for the specified junction temperature range.

Part Context

FAQ

What is the maximum PWM input frequency supported by the PS12034?

The PS12034 supports a PWM input frequency up to 15 kHz, provided the case temperature remains below 100°C and the junction temperature does not exceed 125°C.

How does the PS12034 handle shoot-through protection?

The module includes an arm shoot-through blocking time of 4.0 µs. However, the dead-time must be set externally by the CPU; it is not part of the internal ASIPM functions.

What protection features are included in the control sector?

The control sector includes over-current (OC), short-circuit (SC), and under-voltage (UV) protection. Fault outputs are generated for these conditions, primarily for the lower arms of the inverter bridge.
