- INTRODUCTION The controller 7CH4Q45N / 90N is a 4 quadrant chopper for PMDC motors powered by battery 24/36V for traction applications. The chopper is equipped with a powerful microprocessor for digital control of the speed, current regulation and failures of the motor ; an efficient diagnostics of the failures and wrong wiring connections, programmability of the main parameters . The MOSFET power stage is an “H bridge” configuration operating with PWM. The ripple of the current is very low so the efficiency of the system is very high . The chopper is designed in accordance with the most...
