6 FAQs about [Capacitor busbar length]
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.
What is a bus bar conductor sized for?
Typically, the bus bar conductors are sized for a 30 C self-heating temperature. The lower boundaries in bus bar design require: a minimum conductor thickness to prevent it from melting when the nominal current is applied and a minimum insulation thickness to sustain the intended operating voltage.
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 much current should a bus bar have?
A rule of thumb for bus bar design is to not allow the current density to exceed 5A/mm2 . A higher threshold would mean that a smaller cross sectional area is needed, allowing for a size reduction in the vertical or horizontal directions.
What is a bus bar?
A bus bar is a collection of parallel plates, and an example is given in Fig. 13, where w, t, l, and d indicate width, thickness, and length of each conductor, and the distance between two conductors respectively.
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 .
