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.
