6 FAQs about [Busbar Film Capacitor Process Flow]
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 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.
How to design a bus bar with a small inductance?
It can be seen in (4) that the way to design a bus bar with a total inductance as small as possible is to design it with the maximized mutual inductance and is to maximize the over-lap area of two conductors. Therefore, the laminated bus bar structure is preferred in the design .
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.
How to design a bus bar?
As illustrated by Fig. 1 a bus bar design is composed of several steps. Power semiconductors and DC-link capacitor geometry are chosen to optimize the power density as well as to minimize the bus bar complexity. Some examples are presented at the first step including air and water cooled con-figurations.
