This paper proposes a current control strategy with zero steady-state tracking error for grid-connected boost-inverters. Two boost converters are controlled separately to achieve both output current tracking and balanced output voltages. Based on cascading control and feedback linearization, the inner and outer-loop controllers are derived combining the inversion of boost converter model and the output...
This paper presents an innovative control law for a distributed dc generation supplied by fuel cell (FC) generator. Basically, an FC is always connected with a power electronic converter. This kind of system is non-linear behavior. Classically, to control the voltage, the current or the power in the converter, linearized technique is often used to study the stability and to select the controller parameters...
This paper presents implementation issues of a digital control system applied to a power factor correction (PFC) boost converter rated to a wide range of output power, operating in mixed conduction mode (MCM). The digital control system comprises an input current controller and an output voltage controller. The current controller is formed by two predictive model-based control laws, while the output...
This paper proposes a digital control system applied to a power factor correction boost converter rated to a wide range of output power, operating in mixed conduction mode with fixed switching frequency. The control system is composed of an input current controller and an output voltage controller. The current controller comprises two predictive model-based control laws (one for the continuous conduction...
The circuit principle and harmonic characteristics of peak current mode Boost converter are analyzed, the voltage loop and the current loop are adopted to keep the input current in the same phase with the input voltage. A novel harmonic suppression technology with quasi-square wave compensation is presented in this paper, The input current harmonic components and harmonic contents are reduced by compensating...
In this paper the current control performance of photovoltaic inverters is taken into account. The analytical contribution to the output current due to the grid voltage is analysed and a novel current reference feed-forward is considered in order to compensate for that effect and guarantee a proper current control when feedback current to current controller is measured on the inverter-side inductor...
A grid connected photovoltaic (PV) system, which consists of PV modules, a boost converter with maximum power point tracking (MPPT) controller and a current controlled full bridge inverter with L-C-L filter, is presented in this paper. A simple PIC16F877 microprocessor is used to implement the InCond MPPT controller by adjusted the duty ratio of the boost converter. Then a DC bus voltage controller...
