The phase shift full bridge (PSFB) converter allows high efficiency power conversion at high frequencies through zero voltage switching (ZVS); the parasitic drain-to-source capacitance of the MOSFET is discharged by a resonant inductance before the switch is gated resulting in near zero turn-on switching losses. Typically, an extra inductance is added to the leakage inductance of a transformer ...

In high power converter design, low-inductance busbar connecting DC capacitors and power devices is the main concern to improve the quality of the whole power electronics system. There are several facts which affect the stray inductance of bridge arm. This paper mainly analyzes the influence of DC-power layout on the stray inductance taking a subway traction converter as example. The Psim9.0 so...

Inductance associated with on-chip wires can no longer be ignored as chip operation frequencies increase into GHz regime. Because the magnetic field propagates a very long range, the extraction of wire inductance is not just dependent on the immediate neighboring environment. This paper discusses the various difficulties of extracting inductance of randomly placed wires in a typical chip enviro...

To make three-dimensional (3-D) on-chip interconnect inductance extraction tractable, it is necessary to ignore parasitic couplings without compromising critical properties of the interconnect system. It is demonstrated that simply discarding faraway mutual inductance couplings can lead to an unstable approximate inductance matrix. In this paper, we describe an equipotential shell methodology, ...

Inductance has been identified as an emerging troublemaker of interconnects for the next generation high-speed digital VLSI design. As a result, accurate and fast inductance extraction is of crucial importance. Formulae-based partial inductance extraction method approaches have been widely adopted for inductance extraction due to its simplicity and efficiency. However, there are so many inducta...

The variation of inductance with frequency in high performance power distribution grids is discussed in this paper. The impedance characteristics of the power grid need to be well understood for the design of efficient and robust high performance power distribution grids. The physical mechanisms underlying the dependence of inductance on frequency are discussed. The variation of inductance with...

We propose the concept of an optimal inductance value that can substantially reduce delay of global RLC signals while maintaining good signal integrity (low ringing/overshoot). We exploit the fact that inductance results in faster transition times to improve delay of buffers in global signal lines. We observe that voltage overshoot, slew rate, and total line delay all show strong inflection poi...
