ICS TRIPLEX 9432 Inverter Speed Controller

ICS TRIPLEX 9432 has many advantages such as small size, multi-functions, easy to use, etc. It is suitable for the design and use of inverters with different power. The application of intelligent power modules to design frequency control controllers can greatly simplify the hardware design, shorten the product development cycle and improve the performance of the system. IPM modules launched at different stages, the internal design technology used in the differences in the integration of a variety of protection functions are not the same.

ICS TRIPLEX 9432’s 6-unit IPM module internal IGBT module drive requires 4 independent isolated power supplies, 3 upper bridge arms each require a separate power supply, 3 lower bridge arms share a power supply, which leads to the volume of the system switching power supply and the design of the difficult to increase. The system control part, i.e., MCU or DSP control circuit and power circuit part need to be electrically isolated to ensure the safety of the control circuit. The main signals that need to be isolated are: the 6-channel PWM signals that realise the inverter control.

ICS TRIPLEX 9432 module output fault protection signals; voltage detection signals and so on. Due to the development of power device integration technology, some manufacturers, such as Japan Mitsubishi, Japan Toshiba, the United States Fairchild, etc., using bootstrap power technology, the introduction of a single power supply IPM, which makes it necessary to provide only one way to the IPM module to provide a drive power supply, which provides the possibility of realising the system co-location. ICS TRIPLEX 9432 is a fourth-generation IGBT power module used to drive a low-power (1.5kW) motor. 1.5kW) DC-AC power conversion for motors.
