Aalborg Inverter—A New Type of “Buck in Buck, Boost in Boost” Grid-Tied Inverter

  1. 1. Aalborg Inverter—A New Type of “Buck in Buck, Boost in Boost” Grid-Tied Inverter Presented by IIS TECHNOLOGIES No: 40, C-Block,First Floor,HIET Campus, North Parade Road,St.Thomas Mount, Chennai, Tamil Nadu 600016.

  2. 2. Abstract • This project presents a new family of high efficiency dc/ac grid-tied inverter with a wide variation of input dc voltage. It is a “boost in boost, buck in buck” inverter, meaning that only one power stage works at high frequency in order to achieve minimum switching loss. • The minimum voltage drop of the filtering inductor in the power loop is achieved to reduce the conduction power loss in both “boost” and “buck” mode. • The principle of operation is demonstrated through the analysis on the equivalent circuits of a “half-bridge” single-phase inverter. www.iistechnologies.in Ph: 9952077540

  4. 4. Existing System • In the renewable power generation system, the input dc voltage of the converter may vary greatly. • For example, the output dc voltage of a solar panel will change a lot under different temperature conditions. • To transfer this kind of dc energy into the grid, a two- or three-stage inverter may be required as the power interface, especially for the VSI-based system. If all power stages work at high frequency, the efficiency of the inverter will be inevitable affected. www.iistechnologies.in Ph: 9952077540
  5. 5. Proposed System • In this project, typical full-bridge single-phase grid-tied inverters with the different power sources are introduced. • Next, a new type of “buck in buck, boost in boost” grid-tied inverter is proposed and the operating principle is illustrated through a half-bridge inverter with the equivalent circuits in the different working stages. • Then, the modeling is carried out with a small signal model method. Based on this, an indirect current control method is introduced, when the inverter is working in the “boost” stage. • Finally, simulations and experiments are given to verify the theoretical analysis and the principle of operation. www.iistechnologies.in Ph: 9952077540
