CS-IIC - 2kW Low profile 4 Phase Leg Inverter

PCB CS-IIC

The CS-IIC is a flexible, low-voltage, 4-phase leg integrated inverter system designed for applications requiring a single low-height simple inverter platform. The board includes an on-card IGBT-based power stage and analog conditioned signals that enable operation as a standalone inverter.

The core of the board has a CS-MiniDSP interface that enables a plug-in controller (such as the CS-MiniDSP or CPT-Mini2810) to provide overall system control.

This structure provides a direct upgrade path for the board as a new core processor can be added to the system.

Technical Specifications

 

  • The board consists of 6 major sections:

    • 8 off complementary isolated gate driver PWM outputs, with common fault interrupt
    • 4 phase leg TO-247 FET/IGBT based power stage, with associated input rectifier.
    • Isolated RS-232 serial interface
    • 16 off conditioned analog inputs
    • LCD interface / Keypad interface / Digital I/O
    • Switch-mode power supply to generate all on-card supplies

  • The power stage can be configured as follows:
    • Single bus, Dual-H Bridge inverter (back-to-back DC converter operation)
    • Dual bus, Dual-H Bridge inverter
    • Single bus 3 leg inverter
    • Dual bus 3 leg inverter with single leg buck
    • Single bus 4 leg inverter

    The power stage of the CS-IIC supports operation at a maximum of 5A from a maximum 400V DC bus. The layout supports the use of either FET or IGBT switching devices in a TO-247 package.
