The DC bus also connects to the inverter section of the VFD through a DC link circuit, which controls the flow of current between the DC bus and the inverter. In summary, the DC bus in a VFD is a power distribution system that supplies electrical energy to the inverter, which converts the DC voltage into AC voltage at a variable frequency to control the speed and torque of an …
The dc link bus voltage in VSIs is usually considered a constant voltage source v i. Unfortunately, and due to the fact that most practical applications generate the dc bus voltage by means of a diode rectifier (Fig. 15.37), the dc bus voltage contains low-order harmonics such as the sixth, twelfth,…(due to six-pulse diode rectifiers), and the second if the ac voltage supply features an ...

The DC-BUS was originally developed by Yamar Electronics Ltd. together with the DC-BUS Alliance, for low cost sub-networks in vehicles, using the battery lines for in-vehicle data communication. The DC-BUS converts the digital input data into phase modulated signals, protected against errors generated by noise over the powerline.
Some C-Bus units, for example 5500PC, require 32mA. Some C-Bus units, for example L5508DIA, are self-powering and do not sink current from the 36V d.c. C-Bus network; More than one C-Bus power supply can be connected to a C-Bus network to provide sufficient power to the C-Bus units. The C-Bus power supplies will share the load evenly.
A system with 16-bit address bus can address 216 = 64 KB of memory; A system with 20-bit address bus can address 220 = 1 MB of memory. 2. Data Bus. A collection of wires through which data is transmitted from one part of a computer to another is called Data Bus. Data Bus can be thought of as a highway on which data travels within a computer.
