Small signal modeling approach is used to develop an analytical model for average current-mode controlled interleaved boost converter and the experimental results are presented to evaluate the derived model and performance of designed controller.Abstract:
In high power applications, parallel operation of boost converters is recommended. These paralleled boost converters can be operated in interleaved mode. Interleaved mode of operation improves the steady state and dynamic performance of the system. In this work, small signal modeling approach is used to develop an analytical model for average current-mode controlled interleaved boost converter. The controller is designed and implemented for a 500 W interleaved boost converter prototype. The experimental results are presented to evaluate the derived model and performance of designed controller.read more

Decoupled Current-Balancing Control With Single-Sensor Sampling-Current Strategy For Two-Phase Interleaved Boost-Type Converters
TL;DR: The results show that the voltage-regulation loop and the proposed current-balancing loop are nominally decoupled, and two PI-type controllers can be designed independently and included to implement the proposed DCBC.

Study on a cascaded DC-DC converter for use in building-integrated photovoltaics
TL;DR: A two-stage power-electronics topology is presented for use in a BIPV module-level converter, connected to a low-voltage DC microgrid, and it is shown that the maximum intermediate voltage level in between both converters can be derived from the continuous conduction mode of operation.

A New Isolated Auxiliary Current Pump Module for Load Transient Mitigation of Isolated/Nonisolated Step-Up/Step-Down DC–DC Converter
TL;DR: In this paper, a new isolated auxiliary current pump module (ACPM) is proposed to improve the dynamic response of dc-dc converters under load transients, which can be used as a generic auxiliary module for both isolated and non-isolated step-up/step-down dc-DC converters.

A Sensorless Current Balance Control Method for Interleaved Boost Converters Based on Output Voltage Ripple
TL;DR: The relationship equations between the periodic output voltage ripple and the phase current balance status are analyzed to help an interleaved boost converter prevent imbalanced heat distribution and inductor saturation and improve the output voltage performance and overall system efficiency.
