A paper is dedicated to a special isolated DC/DC converter with active rectifier which in cooperation with an improved active snubber ensures the soft switching of all transistor switches in full load range. Gradually in the paper, at first analysis of proposed isolated DC/DC converter with active rectifier topology is done, and then the proposed active snubber topology is analyzed. At the end, a...
The paper describes design, simulation and laboratory measurement results of the high-frequency softswitching DC-DC converter with half-controlled output fullbridge rectifier.
The paper focuses on a novel type of high frequency soft switching DC/DC converter. The proposed DC/DC converter topology comprises an active rectifier and an active snubber. In the paper, the operation principle of the DC/DC converter with active rectifier is explained and the function of proposed DC/DC converter comprising active snubber is analyzed. For verification of proposed converter operation,...
This paper is dedicated to a special high frequency DC/DC converter with a secondary side active rectifier, which in cooperation with a novel type of active lossless snubber ensures required conditions for soft switching of all transistor switches of the converter in a wide load range. Theoretical analysis of DC/DC converter with active rectifier is done, and operation principle of the proposed soft...
The paper describes design and control of LCL filter with active damping. The LCL filter is used in a single phase grid connected inverter. The performance of two different active damping methods is compared to passive damping by simulation.
This paper presents some considerations on the analysis of an induction heating system and problems that arise during the heating process of steel pieces. The steel pieces under the heating process are modeled to be used as electrical circuit elements of the heating system load. The model of the steel pieces under the heating process consists of a resistive — inductive circuit in order to underline...
A zero-voltage and zero-current switching full-bridge pulse-width modulated dc–dc converter with controlled secondary-side rectifier using a novel nondissipative energy recovery turn-off snubber is presented in this paper. Using a controlled rectifier, a turn-off snubber, and an innovative control algorithm, the circulating current of the converter is eliminated and soft switching for all power switches...
Soft switching full-bridge phase-shifted PWM converter using IGBTs with auxiliary transformer is presented in this paper. Zero-voltage and zero-current switching for all power switches is achieved for full load range from no-load to short circuit by adding active energy recovery snubber and auxiliary circuits. The principle of operation is explained and analysed and experimental results are presented...
