“…These converters operate in critical conduction mode (CRM) or discontinuous conduction mode (DCM), where conduction losses are high, restraining the efficiency and rated output power. Soft switching may be obtained in the converters with zero-voltage transition (ZVT), zero-current transition (ZCT), or active edge-resonant [28][29][30] cells. However, in these techniques, an additional active switch is required to achieve soft switching of the main transistor.…”

High power density, high voltage gain soft-switching PWM DC-DC converter with a tapped inductor is proposed in this paper as a front-end for low-voltage sources in energy generation systems. The leakage inductance is incorporated into the resonant tank, decreasing the component count. The use of the boost capacitor connected in series with the secondary windings of the tapped inductor causes high voltage gain at the low turn ratio of the coupled inductor. By incorporating a resonant passive clamp circuit, not only the voltage spikes on the transistor are restrained, but zero-voltage switching of the transistor and zero-current turning-off of the diodes are obtained. The resonant operation results in low power losses in the switches, providing high efficiency in a wide output power range. Owing to soft-switching operation, the transistor can be driven with a high switching frequency, providing a consolidated design of the high power density converter. The principles of operation of the converter were also analyzed theoretically. Finally, the converter is validated through a laboratory model with a power rating of 300 W and a switching frequency of 200 kHz. 1

Abstract:The paper presents a concept of an active filter with energy storage. This solution can be used for the compensation of momentary one phase high power loads with discontinued power consumption (e.g. spot welding machines). Apart from the typical filtering capabilities, the system's task is also the continuity of the input power from the feeder line and limiting its fluctuation. The proposed by the author's solution can produce measurable economic benefits by reducing the rated power necessary to energize periodically operating loads and improving the indicators of electrical energy quality. The developed method of active power surges compensation enables a flexible approach to requirements concerning the rated power of the point to which the periodically operating loads with high peak current value are connected. The tests were conducted on a simulation model specially developed in Matlab & Simulink environment, proving high effectiveness of the presented solution.
