“…𝐾 𝑖 𝑠 = 𝐾 𝑝 (𝑠 + 𝐾 𝑖 𝐾 𝑝 ) 𝑠 (10) Therefore, the relation between output current to the reference output current using a PI controller can be represented by (11). For determining the current control parameters, Kp and Ki, we can use a commonly procedure by using a frequency response curve analysis to determine the crossover frequency of the system which is able to increase the gain at low frequencies while maintaining a positive PM [25]- [28]. In this study, system parameters as shown in Table 1 are used, where the values of components such as inductors and capacitors are obtained based on calculations to achieve continuous conduction mode (CCM).…”

<span lang="EN-US">This paper proposes a control method for new simplified cascade multiphase direct current-direct current (DC-DC) buck power converters used for low-voltage large-current applications such as cathodic protection. To control the proposed converter, a proportional-integral (PI) controller is used to regulate the output current of the converter. The control scheme analysis is carried out by linearizing the small-signal model of the proposed converter to form the output current transfer functions. This transfer function will be analyzed by using phase and gain margin approach to obtain the control parameters (Kp, Ki, and Ti). Simulation and experiment results are included to show the validity of the proposed concept.</span>

“…The output of the PI controller block is then compared with the inductor current (IL) of the converter which inturn is compared with the sawtooth waveform to produce the PWM pulse. The obtained PWM pulse is then given to the gate of the switches used in the converter [14].…”

One of the main requirements for battery charging applications is constant output voltage and fewer ripples in the output voltage. Boost converters are used in places where the magnitude of the supply voltage is low. But in conventional boost converters, the magnitude of ripple in both the input current and output voltage are high which is not desired. While the input current ripple is reduced in conventional boost converter, the size of the components used is large. In order to reduce the ripples along with reduction in the component size, interleaving concept used. This paper focusses on the operation of four phase interleaved boost converter both in open and closed loop schemes. In the closed loop operation, current control mode is employed because of its faster response to changes along with simpler compensation and high gain bandwidth compared to the voltage control mode. The simulation of the circuit is carried out in MATLAB/SIMULINK and the results are validated for both the schemes.
