(1.1).FPGA PWM Controller


Product Description


This PWM controller is designed based on SPARTAN-6 FPGA controller chip and  this controller can be used  to generate  PWM Signals for SCR, IGBT based power electronics application like DC-AC Inverter ,DC-DC Chopper & SCR  converter based AC/DC/BLDC Switched Reluctance Motor (SRM) control application. PWM output of this controller can be interfaced with Power Module through External cable connection
