INTRODUCTION
The controller 7CH4Q107 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 important EC standards.
