Inverter Based Generators (IBGs) have been increasing significantly in power systems. Due to the demanding thermal rating of Power Electronics (PE), their contribution system Short Circuit Current (SCC) is much less than that from conventional Synchronous (SGs) thus reducing strength and posing challenges protection stability. This paper proposes a Unit Commitment (UC) model with SCC constraint...

Accounting for all possible short circuits in a direct current circuit can prove to be an arduous process. To avoid unintended operation and circuit damage, short circuit protection may be implemented via hardware or software. This paper views the short circuit detection problem as a hardware-software codesign problem in which an inductor installed in a DC circuit is designed alongside a microc...

As MOSFET sizes and wire widths become very small in recent years, in uence of resistive component of interconnects on the estimation of propagation delay and power dissipation can no longer be neglected. In this paper we present formulas of output waveform at driving point and short-circuit power dissipation for static CMOS logic gates driving a CRC load. By representing the short-circuit curr...

This paper proposes a new short-circuit protection method for an IGBT. The proposed method is characterized by detecting not only gate charge but also gate voltage of the IGBT. This results in a shorter protection time, compared to the previous method that detects only the gate charge. A real-time monitoring system using an FPGA, A/D converters, and a D/A converter is used for the proposed prot...

a high accurate and low-voltage analog cmos current divider which operates with a single power supply voltage is designed in 0.18µm cmos standard technology. the proposed divider uses a differential amplifier and transistor in triode region in order to perform the division. the proposed divider is modeled with neural network while tlbo algorithm is used to optimize it. the proposed optimization...

The electric current is omnipresent and indispensable in our life. But there are always threatening dangers connected with it. One of them is the electric short circuit and we have to protect people and facilities from its effects. This protection is often provided by power circuit breakers or motor protective circuit breakers. These devices are able to detect the short circuit, limit the curre...
