Analysis of a Single-Phase Transformerless Bidirectional PFC

چکیده
This paper presents a single-phase transformerless bidirectional power factor corrector (PFC). A capacitor is inserted into conventional full-bridge PFC by connecting the ac line terminal and of DC voltage. The functions this have two roles: to bypass common-mode leakage current from stray capacitor; form an LCL filter reduce inductor ripple. hybrid modulation method employed in PFC. unipolar switching scheme applied modulate PFC, which can achieve high efficiency. Meanwhile, additional blank time low-frequency switches decrease changing speed voltage on capacitor, spike current. performance experimentally verified using 5 kW prototype.

Evaluation of Single Phase Transformerless Photovoltaic Inverters
Transormerless inverters are attractive solution for the grid connected photovoltaic (PV) systems. Unfortunately, it has issues on galvanic isolation between PV systems to the grid. When the galvanic isolation disappears from the PV inverter, leakage currents will flow in a resonant circuit formed by the ground capacitance, the converter, the ac filter and the grid. In order to avoid the leakag...
متن کاملClosed Loop Analysis of Single-Phase Soft-Switching PFC Converter
Generally converter when operated at high frequency results in losses. In this paper a single stage soft switching PFC converter analysis is done. It is developed with a new active snubber cell which provides zero-voltage transition turn ON and zero-current transition turn OFF. This type of converter circuit design does not have additional resonant components. Operating the proposed converter a...
متن کاملApplication of a Remote Lab: Single Phase PFC circuit
Some universities may not have enough resources to provide each student with a separate device in the laboratory. When the number of students in the experiment exceeds the number of devices, then the experiment is carried out by some of the students only while the rest remains indifferent to the experiment. Therefore, not all the students can benefit from the experiment. Nowadays remote laborat...
متن کاملDesign and Analysis of Highly Efficient and Reliable Single-Phase Transformerless Inverter for PV Systems
Most of the PV systems are designed with transformer for safety purpose with galvanic isolation. However, the transformer is big, heavy and expensive. Also, it reduces the overall frequency of the conversion stage. Generally PV inverter with transformer is having efficiency around 92%–94% only. To overcome these problems, transformerless PV system is introduced. It is smaller, lighter, cheaper ...
متن کاملDesign of A Single-Phase Transformerless Grid-Connected PV Inverter Considering Reduced Leakage Current and LVRT Grid Codes
A new single-phase transformerless grid-connected PV inverter is presented in this paper. Investigations in transformerless grid-connected PV inverters indicate the existence of the leakage current is directly related to the variable common-mode voltage (CMV), which is presented in detail. On the other hand, in recent years it has become mandatory for the transformerless grid-connected PV inver...
