Magnetically coupled buck converters

2013 IEEE Energy Conversion Congress and Exposition, 2013
The use of coupled inductors is now a typical approach to decrease the current ripple in multiphase power converters. Minimizing current ripple increases efficiency, while coupled inductors support a fast transient performance at the same time. This paper proposes a new approach: coupling of inductors between the different power converters with ...

Double-Frequency Buck Converter

IEEE Transactions on Industrial Electronics, 2009
Improving the efficiency and dynamics of power converters is a concerned tradeoff in power electronics. The increase of switching frequency can improve the dynamics of power converters, but the efficiency may be degraded. A double-frequency (DF) buck converter is proposed to address this concern. This converter is comprised of two buck cells: one works

Buck Integrated Forward Converter

IEEE 36th Conference on Power Electronics Specialists, 2005., 2006
An integrated converter is a synthesized converter based on the overall system integration, which is simplified by the system objective and can implement the system functions similar to the discrete converters. An integrated converter consists of converter sets; each converter set has a special function defined by the designer.

Digitally controlled buck converter

2004 IEEE International Symposium on Circuits and Systems (IEEE Cat. No.04CH37512), 2004
Digitally controlled step down converter with different control law algorithms is studied in this paper. The state controller is designed to eliminate the start-up overshoot and reduce maximal dynamic error of load change response, but the state controller is not capable of eliminating the steady-state error under the load change condition. By using an

Extended Bucking Range Fifth-Order Buck-Boost Converter

2020 IEEE International Conference on Power Electronics, Drives and Energy Systems (PEDES), 2020
An extended bucking range buck-boost converter of order five, suitable for standalone applications is presented in this paper. It has the attribute of providing finely tuned bucking range with more degree of freedom on duty ratio. The converter provides successful buck-boost conversion with low source current ripple which results in reduced source side

Double Quadratic Buck Converter

2013 Brazilian Power Electronics Conference, 2013
In this paper, a new non-insulated DC-DC converter called Double Quadratic Buck Converter is proposed. This new converter has the advantages of high gain ratio near half range of duty cycle compared to the conventional Buck Converter. The stress voltage over the switches is reduced to half of the value compared to the conventional Quadratic Buck ...

Buck converter controlled by Arduino Uno

2016 39th International Convention on Information and Communication Technology, Electronics and Microelectronics (MIPRO), 2016
The paper presents a buck converter controlled with microcontroller integrated on Arduino Uno board. The control is implemented by use of PI controller embedded on Arduino Uno board. Open loop control-to-output transfer function is obtained from measured step response.

Interleaved zero current transition buck converter

Twentieth Annual IEEE Applied Power Electronics Conference and Exposition, 2005. APEC 2005., 2005
This paper introduces interleaved zero current transition (ZCT) converters where two sets of switches are operating out of phase and share the load power equally. Turn-on transitions at zero current and a significant reduction of the losses associated with diode reverse recovery are accomplished through addition of two small inductors.

Delta-modulated buck-type PWM converter

IEEE Transactions on Industry Applications, 1992
A delta-modulated, buck-type, three-phase pulse-width modulation (PWM) rectifier is described. The rectifier is of the current source type and is intended to be used in conjunction with controlled current inverters. An outer proportional feedback loop regulates the unidirectional output current flowing through the DC link.

A positive output buck boost converter combining KY and SR-buck converters

2015 International Conference on Power, Instrumentation, Control and Computing (PICC), 2015
In most portable electronics equipment's, batteries are used as a source of power. Some efficient power management technique is required in order to get longer battery life. In some batteries, output voltage is not constant so an additional switching power unit is required to get a constant output voltage.
