Multiple inverters connected in parallel is a promising method to upgrade the power capacity of inductive power transfer (IPT) systems. Due to a slight unbalance of the control signals, the inner resistances of the inverters and other uncertainties, circulating currents exist among the parallel units which reduce the reliability of IPT systems. Firstly, the series-parallel resonant tank is empl...

Grid connected inverters are important building blocks in renewable energy conversion systems. In conventional voltage sourcing grid connected inverters, any mismatch between the synthesized output waveforms of the inverters and the grid voltage will generate large erroneous currents unless a fast current feedback is used. The current control requires rather fast sampling rates and considerable...

The aim of study of this paper is design and implementation of a simple and efficient soft switched Pulse Width Modulation (PWM) for three-phase induction motor drives. Soft-switching techniques have gained popularity in recent times because they offer many advantages over hard-switched Pulse Width Modulated inverters such as higher efficiency, higher power density and better performances. The ...

PWM inverter systems have been used in many industrial processes in order to control voltage, frequency and harmonic. On the other hand, High Frequency Resonant DC Link Inverters have been proposed to reduce the switching losses of power devices. This paper reports a simulation developed to use PWM technique with the High Frequency Resonant DC Link Inverter in order to increase the operational ...

The clock distribution network in digital integrated circuits distributes the clock signal which acts as a timing reference controlling data flow within the system. Since the clock signal has highest capacitance and operates at high frequencies, the clock distribution network consumes a large amount of total power in synchronous system. So, a new flip-flop is proposed in a low-swing resonant cl...

A new voltage control method for single-phase full-bridge PWM inverters that having an output LC filter is proposed in this paper. The proposed voltage controller has a capability to realize a zero steadystate output voltage error with fast response. The zero steady-state output voltage error is achieved by using a controller that is derived by using the virtual LC resonant circuit. Fast respon...

The reduction of high harmonic content in the grid side current is achieved by different harmonic compensating techniques. In order to accomplish it, selective harmonic compensation is carried out in grid-connected photovoltaic inverters by means of resonant harmonic compensators. The harmonic compensator shown in this paper is lead lag compensator. This paper shows a systematic design procedur...
