6 FAQs about [Busbars of capacitor bank]
What is a capacitor bank?
Capacitor bank is usually controlled by the microprocessor based device called power factor regulator. Beside, segment installation practice demands protection for capacitor banks. In this case, capacitor banks are connected to the busbars, which supply a group of loads. What’s good in this solution // No billing of reactive energy.
How do you connect a capacitor to a bus bar?
The most common and easiest connection method for a capacitor onto a bus bar is a screw or bolt on connection. Soldering or spot welding connection methods can also be used, but they greatly increase the cost and complexity of the design. In sum, the bus bar design starts along with the power electronics converter design.
Why does a bus bar have a high frequency capacitor?
The laminated structure of the bus bar creates a high frequency capacitor that helps mitigate the noise propagation , , though this unintended filter is likely not enough to completely remove the issue. An unavoidable result of fast switching devices is the high frequency harmonics, termed Electromagnetic Interfer-ence (EMI) .
How is AC current distributed on a bus bar?
The AC current on the bus bar circulates between five DC-link capacitors and three IGBT modules, as a result, the experimental verification for AC current distribution can be implemented by examining the currents in each DC-link capacitors. The current in one of the capacitors is shown in Fig. 17a, while a zoomed in view is shown in Fig. 17b.
What are the different types of bus bar configurations?
Simpler bus bar configurations are shown in Fig. 3c and 3e. Type C consists of a flat bus bar connecting the input and output with the DC-link capacitor, while type E is shaped around the capacitors. In most cases, the ability to share the heat sink between the power semiconductors and DC-link capacitor is lost in this configuration.
How does a bus bar conductor improve DC current distribution?
As illustrated by Fig. 9, DC current distribution is improved by splitting the positive and negative terminals in three. This reduces ohmic losses and evenly spread the heat across the bus bar, which reduces the hot spots. Typically, the bus bar conductors are sized for a 30 C self-heating temperature.
