6 FAQs about [Zhongfu Circuit Photovoltaic Inverter]

Who is Zhongfu Zhou?

Lecturer in Power Electronics, Electronic and Electrical Engineering Dr Zhongfu Zhou is currently a lecturer in power electronics at Swansea University. His research area has been focussing on power electronics converters and applications in renewable energy, transportation, and distribution power systems.

Can a transformerless single-phase PV inverter be controlled in standalone mode?

We propose a high-performance and robust control of a transformerless, single-phase PV inverter in the standalone mode. First, modeling and design of a DC-DC boost converter using a nonlinear back-stepping control was presented.

What is a conversion principle in a power inverter?

The conversion principle in these inverters is the use of a pulse width modulation (PWM) technique to offer a stable sinusoidal output voltage of 220 V AC to the load. Several inverters use power electronic switches such as MOSFET or IGBT in the output stage.

What is a second converter in a PV inverter system?

The second converter is an H-bridge inverter with LC filter having the role of converting continuous to alternative voltage with minimum harmonic distortion and good stability in terms of amplitude and frequency in different values of resistive loads. Block diagram of the proposed PV inverter system. 2.1. PV Array and P&O Algorithm

How to control a single-phase H-bridge inverter?

Secondly, the single-phase H-bridge inverter was controlled by using back-stepping control in order to eliminate the error between the output voltage of the inverter and the desired value, even if there is acute load variation at the output of the inverter.

What is the frequency analysis of the inverter's output voltage?

Figure 21 shows the frequency analysis of the inverter’s output voltage. The fundamental is about 310.7 V at a frequency of 50 Hz, and the THD is about 0.78%.
