Abstract—This paper presents a comprehensive analysis about bus bar design procedure. Some applications in terms of rated power and shape are investigated regarding their particular requirements and challenges. The DC-link capacitor selection is one of the first and most important steps.
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.
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) .
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.
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.
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 .
Simpler bus bar configurations are shown in Fig. 3(c) and (e). Type C consists of a flat bus bar connecting the in-put 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.
