A Soft Switched DC-DC Boost Converter for Use in Grid Connected Inverters
This paper presents a soft-switching DC-DC boost converter, which can be utilized in renewable energy systems such as photovoltaic array, and wind turbine connections to infinite bus of a big power network, using grid connected inverters. In the proposed topology for the DC-DC boost converter, the main and the auxiliary power switches are turned on and turned off with zero voltage switching (ZV...
متن کاملA Protection Circuit for DC-DC Converter with Voltage Doubler
This paper proposes a method to obtain a protected voltage gain by employing a protection circuit for the voltage doubler or multiplier circuit in an isolated tyde DC-DC Converter. The entire set up consists of a phase shift converter with a protected bridge/voltage doubler rectifier on the output side. The operating frequency of the phase shift converter is 20-25kHz (depending on the requireme...
متن کاملA New Circuit Topology for Open Circuit and Short Circuit Fault Tolerant Dc - Dc Converter
This paper describes a new design for a fault tolerant Hbridge dc-dc converter. Open circuit and short circuit fault tolerance is achieved using multilevel converter topology in combination with pulse width modulation control strategy allowing a large set of converter switching states to produce bidirectional power flows at any required output voltage. If two switches fail at particular instant...
متن کاملA Novel DC-DC Converter Based Integration of Renewable Energy Sources for Residential Micro Grid Applications
A novel converter topology interfacing hybrid distributed energy sources and dc bus is proposed in this paper for integration of renewable energy sources with residential micro grid. This converter has low number of active device compared to the converters usually applied to similar application. Multi-Winding transformer is employed for achieving Low input and output current ripple, high voltag...
متن کاملLow-Power CMOS Ramp Generator Circuit for DC-DC Converters
Ramp-signal generators are particularly critical in controlling the frequency and dutycycle of pulse-width modulated (PWM) switching supplies. They are normally implemented with a timed charging current source into a capacitor and a reset switch controlled by two comparators whose reference signals set the lower and upper limits of the ramp. A fast comparator is required to ensure the reset ope...
