MODULATION METHOD TO REDUCE DC BUS HARMONICS CURRENT IN TWO MOTOR

What is a small DC bus motor

What is a small DC bus motor

Nearly all types of DC motors have some internal mechanism, either electromechanical or electronic, to periodically change the direction of current in part of the motor. These motors come in types like brushed, brushless, and coreless, each with special benefits. Small DC electric motors drive innovation in modern technology, powering everything from smartphones to robotic arms. Although a common DC bus configuration is not new and took rise along with the DC to AC drive migration in the 1990s, there are increased implementations across many different industries. The Pennsylvania Railroad's class DD1 locomotive running gear was a semi-permanently coupled pairing of third rail direct current electric locomotive motors built for the railroad's initial New York-area electrification when steam locomotives were banned in the city (locomotive cab removed here).

Reduce bus current

Reduce bus current

The three commonly applied alternatives to parallel termination are operating the bus without termination, implementing an ac-coupled termination, or simply clamping the bus lines to the supply potential, also known as diode termination (Fig. The high magnitude fault currents require high-speed operation of the busbar protection to limit equipment damage. Tripping incorrectly for an external fault may cause large outages, and jeopardize power system. RS-485 continues to be the workhorse in industrial networking, as it has been for more than three decades. Abstract: There is a trade-off between transient performance and line current distortion of the DC bus voltage control of single-phase grid connected voltage source converters. In the case of multiple electric vehicles charging simultaneously, a system optimization control algorithm is adopted to minimize DC-bus current fluctuation by analyzing and reconstructing the DC-bus current in various charging modes.
