Title: Max Berman: Innovator in Electric Vehicle Technology
Introduction
Max Berman is a notable inventor based in Charlottesville, VA (US). He has made significant contributions to the field of electric vehicle technology, holding 2 patents that showcase his innovative approach to current regulation in electric traction motors.
Latest Patents
Berman's latest patents include a "Plug Current Regulator" and an "Electric Vehicle Current Regulator." The Plug Current Regulator is designed for a DC electric traction motor propelled vehicle. It utilizes a microcomputer to control a time-ratio switching regulator, providing a smooth electrical braking function. This is achieved by applying short-duration current pulses to build up braking current, followed by longer durations where current pulses are inhibited. The system compares motor current to a desired braking current, generating an update signal when the actual current drops below the desired level. Filtering is minimized by sampling motor current at intervals that occur after a current pulse is supplied to the motor.
The Electric Vehicle Current Regulator also employs a microcomputer and incorporates accelerator response characteristics similar to those found in internal combustion engine-powered vehicles. This regulator uses a current feedback loop to adjust motor torque according to the accelerator's input. If the required voltage to generate the desired current exceeds the accelerator's displacement percentage, the applied voltage is limited to match the accelerator's position.
