Overview
The CS-IIC is a flexible, low voltage, 4-phase leg integrated inverter system that has been designed for applications requiring a single low height simple inverter platform. The board includes an on-card FET/IGBT based power stage and sufficient digital and analog conditioned signals to enable it to operate, with plug-in CS-MiniDSP /CPT-Mini2810 processor card, as a standalone voltage source inverter without additional circuitry.
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 of the CS-IIC is capable of operation up to 5A at up to a 400V DC bus, and is designed for TO-247 FET/IGBT based switching devices. Sufficient flexibility has been designed in to the power stage to permit operation in any of the following configurations:
- 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
| Alternatively, the system can be operated without the power stage, with the gate drivers supplying a larger capacity (up to 30kVA) and higher voltage (600Vdc) inverter. For even larger external power stage devices, the gate driver output capacity can be increased to 8Apeak using a transistor totem pole pair on the driver output. |  |
