This paper proposes a predictive algorithm for AC-DC three phase converter with active power factor correction. The control proposed does not have current feedbacks and the input current levels are controlled by the DC voltage loop. The main idea of this algorithm is to take the three phases converter like a sequence of two converters working simultaneously and the equations modeled was approximated...
This paper presents the analysis, design and simulation from a simple DC-UPS converter with integrated back-up and automatic transition. This converter makes automatic transition between the main AC and the battery when a failure occurs, and it delivers uninterrupted DC power to the load through two independent power sources of commercial input power and battery power. The converter has the following...

This paper shows, a DC/DC isolated two inductor boost converter, able to start and to operate in permanent regime output voltage from 0 V to 400 V. The characteristics of voltages and currents in the converter make from this topology suitable to be used in applications of high relation between the voltages of input and output as it is the case of the hybrid vehicles (VH). This converter has two auxiliary...
In recent years, many converters are being proposed to be used like bidirectional. Some applications of these DC-DC converters can be battery charger-dischargers, hybrid vehicles, and DC-UPS. In applications like hybrid vehicles a high voltage DC bus to supply power to the motor is usually required. When the DC bus in hybrid vehicle is held by a big capacitor, the selection and design of the converter...

Hybrid vehicles need a high voltage DC bus to supply power to the motor. Architectures of these vehicles usually include a DC-DC bi-directional converter between this voltage bus and the conventional battery. When the DC bus is held by a big capacitor, the selection and design of the aforementioned converter has an additional difficulty since the converter has to work with an output voltage ranging...
