Peak Current Mode Control

A boost power factor correction (PFC) in continuous conduction mode (CCM) by the digital peak current-mode control method with bifurcation control is discussed in this paper. The proposed method is used to prevent the inductor current bifurcation behavior, which is caused by sub-harmonic oscillation when the duty cycle is upon to 50 percent. The bifurcation behavior will increase the inductor current ripple and dissipation, then reduce the Power Factor (PF). Different from the ramp compensation signal performed with analog IC in some papers, a MCU is used to be the controller and also provides the digital compensation function in this paper. With the timer, ADC, PWM, and comparator which are built in the MCU, the necessary parameters will be measured without extra components and additional cost. The proposed method is based on those parameters. In this paper, the MATLAB/Simulink simulation results show the proposed method workable.

The integration of digitization and soft-switch technology can improve the power control accuracy and reduce the volume of power, etc. The response of traditional DC/DC converter's control method was slow and the implementation of digitization was more complex. Therefore, this paper presents a zero-voltage zero-current (ZVZCS) full-bridge DC / DC converter digital control system which adopt parallel current-mode control method and advanced circuit topology combining with ARM processor. Finally, the results of simulation and experimental verify Simulation and the zero-voltage zero-current converter topology is reasonable, parameter design is correct, consistent with the expected theoretical analysis, digital control strategy is feasible.

The Given

This paper presents an implementation of adaptive dual current mode control (ADCMC) on non-inverting buck-boost converter. A verification of the converter operation with the proposed ADCMC has been performed in steady state and during the disturbances in the input voltage and the load resistance. The given simulation and experimental results confirm the effectiveness of the proposed control method.

In this paper, a nonlinear controller is proposed to manage the rotational speed of a full-variable Squirrel Cage Induction Generator wind turbine. This control scheme improves upon tractional vector controllers by removing the need for a rotor flux observer. Additionally, the proposed controller manages the performance through turbulent wind conditions by accounting for unmeasurable wind torque dynamics. This model-based approach utilizes a current-based control in place of traditional voltage-mode control and is validated using a Lyapunov-based stability analysis. The proposed scheme is compared to a linear vector controller through simulation results. These results demonstrate that the proposed controller is far more robust to wind turbulence than traditional control schemes.
