The proposed system is a combination of parallel and series active filters without transformer. It is suitable for applications where size and weight are critical factors. The model of the system is derived and it is shown that the circulating current observed in the proposed active filter is an important quantity that must be controlled. A complete control system, including pulsewidth modulation (PWM) techniques, is developed. Comparisons between the structures are made from weighted total harmonic distortion (WTHD). The steady-state analysis is also presented in order to demonstrate the possibility to obtain an optimum voltage angle reducing the current amplitude of both series and parallel converters and, consequently, the total losses of the system. Simulated and experimental results validate the theoretical considerations.

The continuous proliferation of electronic equipment either for home appliance or industrial use has the drawback of increasing the nonsinusoidal current into power network. Thus, the need for economical power conditioners for single-phase systems is growing rapidly.Different mitigation solutions are currently proposed and used in practice applications to work out the problems of harmonics in electric grids. Over the past few decades, the use of active filtering techniques has became more attractive due to the technological progress in power electronic switching devices, enhanced numerical methods, and more efficient control algorithms. As a consequence, these harmonics can cause voltage distortions, additional losses in the power system, and malfunction of sensitive electronic equipment. For this reason, harmonic restriction standards, have been recommended to limit the harmonic currents injected into the grid by nonlinear loads. Shunt passive filters, consisting of tuned LC filters and highpass filters, have been traditionally used as a simple and lowcost solution to compensate current harmonics. Nevertheless, their performance strongly depends on the grid impedance and can possibly cause the unwanted parallel resonance phenomena with the grid.

For standard configuration (Fig 1), the series converter utilizes a transformer for isolation.The cost and size associated with the transformer makes undesirable such a solution, mainly for office and home environments.

In this way, it has been shown that the proposed configuration presents low WTHD, whose value is, however, higher than that of conventional configuration. This is because of the need to compensate the circulating current io via voltage vo . Method B—series (Method B— parallel) permits to reduce theWTHD in the series (parallel) converter side, but theWTHDof vo is higher than that obtained with Method A. As there was no need to improve one of the converters side (series or parallel converter), the Method A was used to compose the PWM strategy for both simulated and experimental. The proposed transformerless UAPF is controlled according to two proposed PWM techniques objecting the elimination of undesirable circulating current.
