Manufacturer:TI Description: The SN54LS298JCprovides the complete power conversion function for a 7.5hp (5.5kW) variable voltage, variable frequency, AC motor controller. The combines a power assembly SN54LS298JA with a Driver-Plus Board SN54LS298JD. Figure 1 shows the block diagram of the within an AC motor control system. The power assembly contains a 3-phase input bridge rectifier, 3-phase IGBT inverter and a thermistor mounted on an Insulated Metal Substrate (IMS) power board. It is designed for easy mounting to a heat sink. The Driver-Plus Board contains DC link capacitors, capacitor pre-charge function, isolated IGBT gate drive circuits, shutdown protection, isolated trip and current feedback signals, and local power supply. It interfaces to the power assembly via soldered connector pins. Terminal blocks are provided on the Driver-Plus Board for all end-user external connections to the . Output power is Pulse-Width Modulated (PWM), 3-phase, variable-frequency, variable voltage controlled by externally generated user provided PWM controller for inverter IGBT switching. The PWM input signals and feedback signals are opti- cally isolated from the power circuit. The SN54LS298JC offers several benefits to the drive manufac- turer as listed below: • It eliminates component selection, design layout, intercon- nection, gate drive, local power supply, thermal sensing, current sensing, and protection. • It provides committed power semiconductor losses and junction temperatures. • Gate drive and protection circuits are designed to closely match the operating characteristics of the power semicon- ductors. This allows power losses to be minimized and power rating to be maximized to a greater extent than is possible by designing with individual components. • Optimized layout for performance and efficiency is pro- vided. • Low inductance system reduces noise and snubber require- ments. specifications and ratings are given for[ system input and output voltage and current, power losses and heat sink requirements over a range of operating con- system ratings are verified by IRditions. in final testing.] |
