This paper describes a test structure consisting of a ring oscillator and an inverter chain. The load of the elements of the ring oscillator and the inverter chain is programmable. The propagationdelay times measured give a better correlation with real logic circuits. Introduction A test structure often used for the characterization of the circuit performance,in a particular process is the ring...

In this project a new control strategy that can be used together with such a CCC is presented. In the new control system the inverter emulates the operation of a Voltage Source Converter, in the sense that, beside the control of the active power flow through the converter, the reactive power exchange with the AC network can also be managed in order to adjust the alternating voltage of the conve...

Renewable energy, such as solar energy, is desirable for power generation due to their unlimited existence and environmental friendly nature. Reforming of the electricity sector along with various renewable energy promotion policies has increased the importance of small grid connected photovoltaic (PV) systems utilizing single stage single phase inverters. This paper proposes a single-stage inv...

This paper presents a single-phase five-level photovoltaic (PV) inverter topology for grid-connected PV systems with a novel pulse width-modulated (PWM) control scheme. Two reference signals identical to each other with an offset equivalent to the amplitude of the triangular carrier signal were used to generate PWM signals for the switches. The inverter offers much less total harmonic distortio...
