“…The integrated inductors [68] can be divided into noncoupled inductors [69] and coupled inductors [70]. The integrated inverse coupled inductors can not only reduce current ripple by increasing steady state inductance, but also increase transient respond by decreasing transient inductance [41], [71].…”

“…Multiphase technology with the interleaved boost converter topology has attracted the attention of many researchers in recent years. This method implements phase-shifted pulse-width modulation (PWM) signals to control the metal-oxide-semiconductor field-effect transistors (MOSFETs) and is often used in designs that require parallel components [17]. This article focused on the two-phase DC-DC boost converter, in which the PWM signals of the two-phase boost converter are assigned as a 180-degree phase shift at each level to turn on and off the MOSFETs.…”

This paper presents modeling and hardware implementations of a two-phase DC-DC boost converter by using the system identification approach. The main objective of this research was to study new methods to obtain the values of the constants for the proportional-integral (PI) controller. Existing methods are time-consuming, since the values of the constants for the PI controller need to be calculated. The system identification approach for the closed-loop boost converter saves more time. This method has the fastest technique to find constants Kp and Ki for the closed-loop two-phase boost converter. To model a two-phase boost converter using the system identification approach, input duty cycle and output voltage are collected in the time domain data. In this study, the transfer function (TF) model, the autoregressive moving average with exogenous (ARMAX) model and the output-error (OE) model were used to generate a mathematical model. To perform the closed-loop analysis, constants Kp and Ki were obtained based on the generated mathematical model from the system identification approach. The result from the experiment shows that the percentages of overshoot for the TF, ARMAX and OE models were 19%, 25.36% and 24.6%, respectively. The output voltage ripples obtained for all three models were less than 5% of output voltage.

“…Benefits of such control methods include reduction of size, losses and cost of the input and output filter, reduction of current stress of the DC bus capacitor, improved dynamic performance and increase in the power capacity of the converters. Interleaved DC-DC converters are used in various applications: as voltage regulation modules [2], [3] renewable applications [4], [5], [6], [7], [8], traction applications [9]- [14] and in the other application areas. In this case benefit from utilizing interleaved topology is possibility to reduce the size and losses in output inductors.…”
