Abstract :
This paper presents a control technique based on input and output AC power synchronization to reduce the low frequency AC power and the DC-link voltage fluctuation of a single-phase full-bridge converter. The control technique is based on a technique in which the load voltage is synchronized with the input grid voltage for both constant (Mode I) and variable (Mode II) phase angle. Such approach allows for a reduction in the capacitor size. A capacitor bank design approach is also proposed. The technique has been achieved for the same input and output converter frequency. Simulated and experimental results are addressed.
