Switching Converters with Wide DC Conversion Range
نویسنده
چکیده
In dc-to-dc conversion applications that require a large range of input andlor output voltages, conventional PWM converter topologies must operate at extremely low duty ratios, which limits the operation to lower switching frequencies because of the minimum ONtime of the transistor switch. This is eliminated in a new class of singletransistor PWM converters featuring voltage conversion ratios with quadratic dependence on duty ratio. Practical circuit examples operating at 0.5 MHz are described.

Investigation of Novel Transformerless Converters for DC Microgrid: Design and Analysis
This paper proposes two new soft-switching transformerless converters with high voltage conversion ratio. These proposed converters achieve soft-switching each with a single auxiliary resonant cell. The merit of these converters is reduced switching losses with lesser number of devices. The main switching devices are turned off with zero current switching (ZCS). Apart from the soft-switching fe...

In this paper, a boost converter with a clamp circuit is proposed for high intensity discharge (HID) lamp application. The clamp circuit provides zero voltage turn on for both main and clamp switches. Compared to conventional boost converters, the proposed converter has the following advantages: (i) high voltage gain without suffering from extreme duty ratio, (ii) low stress on the switches and...
متن کاملZero-current-transition Converters for High-power-factor Ac/dc Applications
Zero-current-transition, discontinuousconduction-mode (ZCT-DCM) converters are introduced in this paper. Compared to hard-switching (PWM) converters in DCM, the ZCT-DCM converters have similar current stresses and conduction losses, and much reduced turn-off switching losses. At the expense of increased voltage stresses, zerocurrent/zero-voltage switching is maintained for a wide range of loads...

Phase-shifted converters are practically important to provide high conversion efficiencies through soft-switching techniques. However, the limitation on a resonant inductor current in the converters often leads to a non-fulfillment of the requirement of minimum load current. This paper presents a new power electronics control technique to enable the dual features of bi-directional power flow an...
