PS12032

Overview

The Powerex PS12032 is an Application Specific Intelligent Power Module (ASIPM) rated for 5 Amperes and 1200 Volts. It integrates a three-phase IGBT inverter bridge, a rectifier bridge for AC-to-DC conversion, high-voltage integrated circuits (HVICs), and protection circuitry into a single compact package. Designed for small inverter applications operating up to 20 kHz, the module utilizes application-specific HVICs to reduce inverter size and overall design time.

Feature Summary

• Integrates a three-phase IGBT inverter bridge and a rectifier bridge for complete power conversion stages.
• Includes built-in high-voltage integrated circuits (HVICs) providing gate drive, system control, and protection functions.
• Features direct connection capability to DSP or CPU controllers via dedicated input terminals.
• Incorporates a built-in thermistor for thermal monitoring and management.

Applications

• Smart Motors
• General Purpose Inverters
• Small Motor Control

Procurement Notes

Verify the specific part number PS12032 against official Powerex documentation to confirm current manufacturing status and technical specifications. Ensure that any ordering suffixes do not alter the functional characteristics unless explicitly documented by the manufacturer. Cross-reference terminal pinouts and isolation voltage ratings with the latest datasheet before integration.

Selection Notes

Select this module for designs requiring a compact solution for three-phase inversion and rectification. The integrated HVICs simplify driver design by handling gate drive and protection logic. Verify that the required switching frequency does not exceed the specified limits for the intended thermal environment and load conditions.

Part Context

This component belongs to the Powerex Intellimod™ series of Application Specific Intelligent Power Modules. These modules are engineered to consolidate power devices, gate drivers, and protection circuits into a unified package, facilitating faster development cycles for inverter-based systems while maintaining robust electrical performance.

FAQ

What is the maximum recommended PWM input frequency?

The maximum recommended PWM input frequency is 15 kHz when the case temperature is maintained at or below 100°C and the junction temperature is within the specified limit.

How does the module handle over-current protection?

The module includes internal over-current detection with a trip level typically around 7.0 Amperes. Upon detection, it triggers a fault output signal and shuts down the gate drive to protect the IGBTs.

Is there a built-in mechanism for shoot-through prevention?

Yes, the module features 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 ASIPM internal automatic functions.
