Applications

  The 0.17Cprovides the complete conversion function for a 0.75hp (0.56kW) variable frequency, variable voltage, AC motor controller. The combines a power module 0.17A with a Driver-Plus Board 0.17D. 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 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, protetion circuitry and local power supply. It is designed to mate with a controller board through a single row header. Terminal blocks are provided on the Driver-Plus Board for all end user line input and motor output.   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 micro-controller.   The 0.17C offers several benefits to the drive manufacturer listed below: • It greatly simplifies component selection, design of layout,   interconnection, 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   semiconductors. 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 conditions.   system ratings are verified by IR in final testing.]

Features

Devices are 100% production tested at TA = +25C. All temperature limits are guaranteed by design. Input Offset Voltage is defined as the center of the input-referred hysteresis zone. Specified for VCM = 0. See Figure 1. Trip Point is defined as the input voltage required to make the comparator output change state. The difference between upper (VTRIP+) and lower (VTRIP-) trip points is equal to the width of the input-referred hysteresis zone (VHYST). Specified for an input common-mode voltage (VCM) of 0. See Figure 1. Inferred from the CMRR test. Note that a correct logic result is obtained at the output, provided that at least one input is within the VCMR limits. Note also that either or both inputs can be driven to the upper or lower absolute maximum limit with- out damage to the part. Tested over the full-input voltage range (VCMR). Differential Propagation Delay is specified as the difference between any two channels in the 0.17/0.17 (both outputs making either a low-to-high or a high-to-low transition). Propagation Delay Skew is specified as the difference between any single channels output low-to-high transition (tPD+) and high-to-low transition (tPD-). Latch specifications apply to 0.17 only. See Figure 2.
