manufacturer:linear description: the protection circuitry receives current signals from shunts in positive and negative dc bus rail for earth/ground fault and short-circuit conditions. any earth-fault signal is fed through an opto-isolator to the protection circuitry. current signal from negative dc bus rail is provided on the j3 connector as current feedback, i fb (0.045v/a). if filtering of this signal is required, it should be done by adding a high-impedance buffer stage between signal and filter. dc bus voltage is scaled down to provided a voltage signal on the j3 connector as voltage feedback, vfb (0.023 x bus voltage). thermal sense signal for over-temperature protection is obtained from a thermistor housed inside the power module. the thermistor activates the latch if the temperature of the power modules ims substrate exceeds a set level. the system is designed for 150% overload for one minute while operating with the specified heat sink. the external microcontroller should shut off pwm signals if the overload condition persists for more than one minute. the switching power supply employs the ir2152s self- oscillating driver chip in a buck regulator topology to deliver nominal 15v and 5v dc outputs, referenced to the negative dc bus (n). the power supply feeds the gate drive and protection circuits. the 15v and 5v outputs are available on the control interface connectors (j3) vcc and vdd pins for external microprocessor and control logic supply. |
