manufacturer:linear description: the ltc1293bcncprovides the complete power conversion function for a 3hp (2.2kw) variable-frequency, variable-voltage, ac motor controller. the combines a power assembly ltc1293bcna with a driver-plus board ltc1293bcnd. figure 1 shows the block diagram of the within an ac motor control system. the power module contains a 3-phase input bridge rectifier, 3- phase igbt and diode, 3-phase igbt inverter, current sense shunts, and a thermistor. it is designed for easy mounting to a heat sink. the driver-plus board contains dc link capacitors, capacitor soft charge function using ntc thermistor, surge suppression movs, igbt gate drivers, dc bus voltage and current feedback signals, protection circuitry and local power supply. it is de- signed to mate with a controller board through a single row header. terminal blocks are also provided on the driver-plus board for all end-user line input, motor output, and brake resis- tor. output power is pulse-width modulated (pwm), 3-phase, variable-frequency, variable voltage controlled by an externally- generated user-provided pwm controller for inverter igbt switching. the power supply offers the user non-isolated 5v and 15v to power the microcontroller. the ltc1293bcnc 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. • 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. • it reduces the effort of calculating and evaluating power semiconductor losses and junction temperature. • it reduces the manufacturer's part inventory and simplifies assembly. [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- ditions.system ratings are verified by ir in final testing.] |
