Average current-mode control, as shown in Figure 1, is common in continuous-conduction-mode (CCM) power factor correction (PFC). It has two loops: a voltage loop that works as an outer loop and a ...

This paper proposes a delay-affected two-degree-of-freedom proportional-integral-derivative (DE-2DOFPID) controller for accurate speed regulation of brushless direct ...

Due to their versatility, ease of design, and low cost, flyback converters have become one of the most widely used topologies in power electronics. Its structure derives from one of the three basic ...

In DC-DC converter design, ensuring stable and reliable operation is crucial, especially in high-power applications such as renewable energy systems, electric vehicles, and industrial power supplies.

In this study, control methods for the converter inner current loop of HVDC systems were evaluated by comparing different combinations of PI controllers and lead-lag compensators. The evaluation was ...

This paper explores pole placement techniques for the 4 th order C1 DC-to-DC Buck converter focusing on optimizing various performance metrics. Refinements were made to existing ITAE (Integral of Time ...

This article introduces a model-based robust control framework for electrohydraulic soft robots. The methods presented herein exploit linear system control theory as it applies to a nonlinear soft ...

To solve the delay problem of a unified power quality conditioner (UPQC) system during the separation of the fundamental positive-order components and to better filter out the DC and harmonic ...

The two methods for testing DC-DC stability. Frequency behavior with buck VM and CM architectures. Compensators for VM and CM architectures. Aligning the time constants of the LC filter to close the ...

Active current sharing methods 1,2 are typically employed for proper current sharing. This indicates that each supply has an internal current share controller. Figure 1a shows an example of a ...

Recently I stumbled across a research paper describing how an Analog-to-Digital (ADC) converter can be implemented almost entirely within an FPGA. The paper illustrated how a differential input LVDS ...

The second order dc-to-dc buck converter with input LC filter is widely used in industry. An alternative 4th order converter which has advantages in terms of control design leading to better transient ...
