An Improved Control Method Based on Modified Delta-Sigma Modulator for Buck Converter

This paper proposes an improved control method based on modified Delta-Sigma Modulator (DSM) to enhance transient response and improve harmonic contents of buck DC-DC converter. The main advantages of the proposed method are improving the output voltage frequency spectrum, correction of the output voltage harmonic contents and sideband harmonics, reduction of switching noise peaks at the output...

High Boost Isolated DC-DC Converter with Controller

This paper presents high boost isolated dc-dc converter with closed loop control to provide high voltage regulation control suitable for renewable energy source. The circuit consists of active clamp circuit and boost converter with isolated transformer. The circuit employs capacitors are charged in parallel and discharged in series by isolated transformer inductors. The active clamp circuit is ...

A modified high step-up non-isolated DC-DC converter for PV application

A non-isolated high voltage gain DC-DC converter has been presented in this paper. The boost, SEPIC and modified SEPIC converters were nalyzed and their performance was compared with the proposed converter. The proposed converter has been designed for the input voltage of 5 V and an output voltage of 150 V with 100 W output power. The efficiency of the converter obtained was 92.5%, which is hig...

The New Bridge Converter Control Method

The article describes a new control method of transistor power bridge converter. It is a new one, because of some original solutions and its difference in comparison to existing methods. It’s irrelevant of load, similar to the “phase shifted” control method. It is easy to realize using ordinary electronic elements. A significant advantage of method is the possibility of permanent output current...
