This paper explains the implementation of a small-signal model for new five-level series resonant inverter structure. The proposed circuit combines advantages multilevel inverters and characteristics physical phenomena, resonance. offers possibility to design linearized linear time-invariant (LTI) around an equilibrium point based on first-order Taylor series. After that, performance its are ev...

Microgrid stability issues are classified into three categories: transient, voltage, and small signal (SSS). Small variations in the load demand perturbations control system line impedance parameters can cause instability, which be avoided by performing an SSS analysis. This paper focuses on investigating impact of passive filter a MG grid-connected mode. Therefore, was represented mathematical...

The effect of optical illumination on DC and dynamic performance of Si1-xGex based double drift region (DDR) (p+pnn+) IMPATT diode operating at W-Band is investigated and compared with its Silicon counterpart. Top Mounted (TM) and Flip Chip (FC) structures are chosen and the composition of photocurrent is altered by shining light on the p+ side and n+ side of the device through optical windows....

This paper describes the design of an X-band balanced low noise amplifier (LNA) using an available HJFET device. The balanced LNA consists of a pair of electrically similar transistors whose input and output signals are divided or combined by 3 dB two-stage Wilkinson power dividers. The proposed balanced LNA is fabricated and measured. The measured results show that the noise figure is 1.30 dB ...
