CHOPPER CONTROL EQUIPMENT WITH REGENERATIVE BRAKE SUPPLIED TO TORONTO TRANSIT COMMISSION

An experimental conversion of 6 conventional resistor-controlled subway cars to chopper control was made. The 2-phase 600 v dc chopper equipment is capable of controlling eight 86 kw traction motors (per two cars) and provides 65% weak field controlling regenerative braking. All major components are designed to withstand severe service conditions in temperatures as low as -30 C. Computer simulation indicates that electric cars using this control system consume about 30% less power than resistor-controlled cars.
