PS12036: The Comprehensive 1200V ASIPM Solution
How can you condense a 2.2kW motor drive's power stage and protection circuitry into a single PCB footprint without compromising 1200V reliability? The Mitsubishi PS12036 ASIPM consolidates a 3-phase AC-to-DC converter, IGBT inverter, and DSP-ready HVIC protections into one comprehensive 1200V, 15A package. 1200V | 15A | 2.2kW inverter capacity. Key benefits: Minimizes PCB footprint complexity. Eliminates external optocoupler stages. Direct connection to a DSP is achieved through the 5V CMOS/TTL compatible Schmitt Trigger inputs built into the internal HVIC. For space-constrained 2.2kW/400V VFDs requiring acoustic noise-less operation, this 1200V ASIPM is the definitive power stage choice.

Technical Deep Dive
Architectural Anatomy: The HVIC and CBI Topology Advantage
Designing a robust power stage conventionally requires piecing together separate diode bridges, IGBT arrays, and complex gate drive circuits. The Mitsubishi PS12036 completely disrupts this paradigm by implementing an Application Specific Intelligent Power Module (ASIPM) architecture. It is structured around a Converter-Inverter (CBI) topology, meaning both the 3-phase AC input rectification and the high-frequency DC-to-AC output stages are encased in a single insulated 28-PowerDIP module.
To understand the sheer efficiency of this design, consider the internal High-Voltage Integrated Circuit (HVIC). The internal HVIC acts as an embedded translator, instantly converting fragile 5V DSP signals into robust high-voltage gate drive pulses. This is a massive leap forward compared to traditional discrete designs. Assembling a motor drive with discrete parts is like building a custom PC from scratch—it requires meticulous component matching and extensive trace routing to prevent noise interference. An ASIPM is like a pre-assembled industrial workstation; the crucial high-voltage pathways, simplifying reliable power design and protections, are already optimized and sealed inside. This integration ensures that the HVIC gate drive delivers synchronized, low-jitter switching for up to 20kHz operations.
Application Scenarios & Value
Deploying the PS12036 in Compact Industrial Smart Motors
Engineers architecting modern Variable Frequency Drive (VFD) systems face a constant battle against physical space and thermal constraints. A prime scenario for the PS12036 is the development of compact VFDs mounted directly onto the chassis of factory CNC spindle motors. In these environments, minimizing the PCB footprint is mandatory. By leveraging the module's internal AC-to-DC converter stage, designers eliminate the need for a separate bulky rectifier block, drastically shrinking the overall inverter volume.
Furthermore, because the module interfaces directly with the DSP controller, the BOM reduction is substantial. While this model operates flawlessly in 400V line applications, for systems utilizing lower 200V mains, the related PM15CMA060-1 provides a suitable 600V rating, ensuring you match the voltage class to your specific regional power grid.
From a field engineering standpoint, deploying a unified module rather than scattered discrete blocks drastically minimizes parasitic trace inductance and accelerates compliance testing. By centralizing the thermal interface to a single baseplate and letting the built-in logic handle short-circuit faults instantly, you guarantee long-term field survivability and a significantly reduced total cost of ownership for industrial deployments.
