Analysis and design for interleaved ZCS buck DC-DC converter with low switching losses
ABSTRACT: This paper presents an interleaved buck DC-DC converter using zero current switching (ZCS) resonant with additional inductor and capacitor that mainly used for battery charging applications. The proposed novel converter has advantages of its simplicity, low cost, high efficiency and behaviour of easy control under the (ZCS) condition so that reducing the switching losses. Therefore, the proposed converter offers ... إقراء المزيد

Performance Evaluations of Interleaved ZCS Boost DC-DC Converters Using Quasi-Resonant Switch Blocks for PV Interface
ABSTRACT: This paper presents a novel circuit topology of voltage source multi resonant ZCS interleaved boost DC-DC converter with auxiliary quasi-resonant lossless inductor snubbers and capacitor snubbers. It uses two feedback loops, similar to current mode control, one for slow outer loop and the other for faster inner PWM control loop. To improve the transient response of the 2-cell converter ... إقراء المزيد

CONTROL TECHNIQUES FOR DC-DC CONVERTERS WITH IMPROVED PERFORMANCE
ABSTRACT The switched-mode DC-DC converters are some of the most widely used power electronics circuits for its high conversion efficiency and flexible output voltage. These converters used for electronic devices are designed to regulate the output voltage against the changes of the input voltage and load current. This leads to the requirement of more advanced control methods to meet the ... إقراء المزيد
