A soft-switched inverter is derived from the passively clamped quasi-resonant link circuit with three different clamps: coupled inductor, diode clamp and coupled inductor and capacitor. The proposed soft-switching inverter is formed from the traditional pulse-width modulated (PWM) inverter by simply augmenting with auxiliary resonant circuits, and the soft switching is achieved through applying...

High pressure inductively coupled plasma (ICP) sources are used in numerous applications, in particular for the testing of thermal protection materials used to protect space (re-)entry vehicles. The planetary gas is injected in a swirling, annular way into a heat-resistant quartz tube, surrounded by an inductor. A radio-frequency electric current runs through the inductor and induces a secondar...

The multi-phase implementation in the QR (quasi resonant) ZCS (zero current switching) SC (switched capacitor) bidirectional DC-DC converter structure has been proposed to reduce current ripple, switching loss and significantly increase the converter efficiency and power density. This approach provides a more precise output voltage to obtain voltage conversion ratios from the double-mode versus...

This paper presents the design of five-stage current controlled inductor-less ring oscillator that were simulated in Silterra 0.18um CMOS Technology with oscillation frequencies up to 5.99 GHz. The design uses cross coupled MOS devices along with active inductor (thus inductorless) and controlled by current source to aid in switching speed and to improve the noise parameters. The simulations sh...

The Conventional Boost Converters is not possible to obtain the high voltage gain. In this paper a DCDC boost converter is proposed for achieving high voltage gain and to reduce the harmonic content in the output side. The circuit diagram of the proposed converter is consists of coupled inductor. Therefore the voltage stress on the active switch is reduced due to the presence of the inductor an...

In this paper, an improved passive snubber is investigated in a single-phase single-stage full-bridge boost power factor correction (PFC) converter, by which the voltage spike across primary side of the power transformer can be suppressed and the absorbed energy can be transferred to the output side. Compared with the basic passive snubber proposed earlier, the two single-inductors are replaced...
