A New High Efficiency Tri-State Boost Converter

Conventional two-state dc to dc voltage converters have in their small signal transfer function a right half planzero in pole-zero plane whichthis zero result in speed reduction and lowfrequency operation, especially, because position of the zero is not fixed andmovesby the load variation. To remedy this problem the tri-state boost converters have been introduced. These converters haven’t the m...

Zvt-zct Pwm Dc-dc Boost Converter with High Efficiency

An improved active snubber cell is proposed for ZVT-ZCT PWM DC-DC boost converter. Zero voltage transition (ZVT) turn on and zero current transition (ZCT) turn off is provided by this active snubber cell. There is no extra current or voltage stresses on the main switch. Also, zero current switching (ZCS) turn on ZCT turn off is provided for the auxiliary switch. Although there is no extra volta...

Boost Converter Efficiency Through Accurate Calculations

P ortable battery-operated electronic equipment is becoming packed with more features requiring larger amounts of power, leading to decreased operating times between battery charges. Innovations such as dynamic backlight control, where the liquid crystal display’s (LCD) backlight power is reduced based on screen content, and automatic voltage scaling, where a microprocessor’s frequency and supp...

A Cascaded Boost-Buck Converter for High-Efficiency Wireless Power Transfer Systems

Wireless power transfer (WPT) has attracted an ever increasing interest from both industry and academics over the past few years. Its applications vary from small power devices such as mobile phones and tablets to high power electric vehicles, and from small transfer distance of centimeters to large distance of tens of centimeters. In order to achieve a high efficiency WPT system, each circuit ...
