Presented is a transistor-level implementation of a floating and tunable CMOS active inductor. It is based on the classical gyrator-C topology and is enhanced by adding an internal offset reduction mechanism to guarantee functionality also for unbalanced DC conditions. The realised inductance can be programmed for values between 685 μH and 12.4 mH and is designed to be implemented using standard CMOS...
This paper joins a series of papers dealing with high-speed power system emulators. It clarifies the last details about the system level of the AC emulation approach by analyzing and quantifying the systematic errors introduced during modeling. Thereby a new optimized generator model has been developed. Its main advantage is improved stability. The functionality of this optimized model is proven by...
This paper presents two different demonstrators of electronic hardware platforms, dedicated to power system emulation. They use DC emulation approaches of an AC power system. Both demonstrators focus on the speeding-up of the temporal analysis of a power system. The first demonstrator proves the feasibility of such programmable hardware. Moreover, comparison with a reference numerical simulator is...
An analog electronics emulation solution is investigated in order to assess the state of a power system facing dynamic phenomena such as the transient stability. Two approaches are studied: DC emulation and AC emulation. Both are intended to be integrated on VLSI submicron CMOS silicon technologies. This implementation has the advantages of presenting low cost, fast simulation time that is independent...
