IEEE transactions on industry applications, 2019
This paper proposes a power controller used for three-phase inverters with small dc-link capacitors fed by a single-phase diode rectifier. The effect of the reactive power was investigated based on a power flow analysis between a dc-link and three-phase ...

Intelligent grid-interactive single-phase inverter
2018 IEEE 59th International Scientific Conference on Power and Electrical Engineering of Riga Technical University (RTUCON), 2018This work presents the design and implementation of a Sinusoidal Pulse Width Modulation (SPWM) single phase grid-interactive inverter with the ability to operate both in stand-alone and grid-connected modes. The proposed design consists of a Voltage Source Inverter (VSI), single power stage full-bridge topology with a low frequency (LF) transformer ...

IEEE transactions on industrial electronics (1982. Print), 2019
Two-stage single-phase inverter system has found many applications in distributed generators and grid-connected systems. However, the existence of double-line frequency ripple on the dc-bus voltage due to single-phase inverter's operation has given rise ...

Single Phase Bidirectional H6 Rectifier/Inverter
IEEE Transactions on Power Electronics, 2019Transformerless photovoltaic (PV) inverters are more widely adopted due to high efficiency, low cost, light weight, etc. However, H5, HERIC, etc., transformerless PV inverters do not have the bidirectional capability for a solar energy storage system in the future.

Single phase hybridised seven-level inverter
2015 International Conference on Innovations in Information, Embedded and Communication Systems (ICIIECS), 2015Multilevel inverters are much superior to conventional two level inverters for their improved performance. This paper presents a novel single phase seven level inverter to reduce harmonic content in output voltage and load current. Operation principle and switching scheme of proposed inverter are analysied in detail.

A Single-Phase Transformerless Common-Ground Type PV Inverter With Active Power Decoupling
IEEE transactions on industrial electronics (1982. Print), 2023To solve the problems of existing nonisolated PV grid-connected inverters, such as leakage current, power pulsation, and harmonic current, a single-phase common-ground-type nonisolated grid-connected inverter with power decoupling capability is proposed ...

Single phase ZVS PWM NPC inverter
XI Brazilian Power Electronics Conference, 2011This paper presents a zero-voltage, pulse width modulated, NPC inverter, with active voltage clamping using only two auxiliary switches. The structure is particularly simple and robust. It is very attractive for high-power applications, single or multiple phases, due to neutral point accessible at the NPC topology.
