The generator is part of a motor-generator set, the motor of which is supplied from the power source connected to the motor.
generator is connected in series opposed to the polarity of a d.c. Losses measured are discussed, as are waves forms and their harmonic content, the measurements of resistance and inductance, EV motor/chopper application criteria, and motor design considerations.ĭC Motor control using motor-generator set with controlled generator fieldĪ d.c. Two motors, differing in design detail, commercially available for EV use were tested. Criteria for the design of such a facility are presented. A test facility utilizing a dc generator as a substitute for a battery pack was designed and utilized. The EV motor application is characterized by the following requirements: (1) the need for highest possible efficiency from light load to overload, for maximum EV range, (2) large short time overload capability (The ratio of peak to average power varies from 5/1 in heavy city traffic to 3/1 in suburban driving situations) and (3) operation from power supply voltage levels of 84 to 144 volts (probably 120 volts maximum). Motors for electric vehicle (EV) applications must have different features than dc motors designed for industrial applications. Losses in chopper-controlled DC series motors self-excited DC motor shunt, series, compound and separately exci. The experimental setup was made by connecting the boost converter circuit with four types of DC motor, i.e. The Boost converter is designed using DC chopper and DC chopper cascade configurations. In The Proceeding of The 2nd International Symposium on Smart Material and Mechatronics 2015 This paper presents the design and testing of a boost type DC/DC converter circuit, which can be used for DC motor control applications. Samman, Faizal Arya Akil, Yusri Syam Noor, Nirwan A. (author)ĭesign and Testing of Boost Type DC/DC Converter for DC Motor Control Applications Waveforms for each load current and converter current are investigated for different modes of operation. The performance characteristics such input power factor, supply current distortion factor, supply current fundamental power factor, torque speed, and motor current ripple factor have been derived and studied for both constant firing angle and constant load factor have been derived and studied for both constant firing angle and constant load power of one motor. The critical firing angle at which the mode of operation changes from one mode to another is deduced. Different modes of operation (continuous and discontinuous converter currents) are considered. The converter loads combination is simulated on a digital computer. This paper is concerned with the detailed study of the performance characteristics of an AC- DC full-controlled converter supplying two DC-series-motor loads. Series motors are extensively used in many applications that require both high starting torque and essentially constant horse power. Phase-controlled converters are widely used because these converters are simple, less expensive, reliable, and do not require any communication circuit.
