“…And the output of phase detection can be seen in Figure. The waveform of a single-phase AC voltage and the output waveform of the phase detection circuit is shown in Figure 9 where if the AC waveform (output of the CT transformer) is at the zero-crossing position, this circuit will detect that position with a high condition [8]. Conversely, when the AC wave is in a value position, it will be in a low condition.…”

Rice is one of the most important cultivated plants in human civilization. One of the most important post-harvest processes is drying. Therefore, we need a drying process with an artificial heat source that can be adjusted to achieve constant heat according to the temperature characteristics of the rice. By applying the Fuzzy-MIMO control system, rice drying is expected to work quickly without damaging the rice foam. Fuzzy-MIMO system is translated into a rule based on the fuzzy algorithm that has been created. The fuzzy-MIMO method used is the Sugeno method with input temperature errors and humidity errors and outputs in the form of heat and wind gusts. The temperature sensor used has an error factor of 3.61%. The expected control system is a heating system and a motor to regulate the wind gusts in the drying chamber. The total drying time produced is 240 seconds with a moisture content of 15.2%. Drying time is influenced by the initial moisture content of rice.

“…Buck converters, also known as step-down converters, are widely used in applications where a regulated voltage needs to be obtained from a higher voltage source. Examples of such applications are industrial applications [ 1 , 2 ], like motor drives or factory automation [ 3 , 4 ], telecommunications [ 5 ], solar power systems [ 6 ], automotive [ 7 ], and voltage regulators [ 8 , 9 , 10 , 11 , 12 ]. This ability to reduce the voltage level is essential in many electronic devices, and in the literature, different topologies, starting with the classical step-down buck converter [ 13 ], other types of non-isolated [ 14 , 15 ] converters or isolated step-down converters [ 16 , 17 , 18 ] can be found.…”

This paper aims to outline the process of dimensioning a controller tailored for a fourth-order step-down converter. In order to conduct a thorough small-signal analysis, it is imperative to find the state–space model in matrices form. Given its fourth-order nature, the control-to-output transfer function also aligns with this order, although its degree is ultimately reduced to a second-order using the tfest function. It is remarkable that the design of the type III error amplifier assumes a central position in the overall controller design process. The theoretical analysis was then subjected to rigorous validation via simulation, with particular attention paid to the step response in both input voltage and output resistance. This study developed from the desire to validate the efficacy of reducing the control-to-output transfer function degree using the tfest function, aiming to highlight a fourth-order converter to which controller design theory can be applied, related to that for a second-order converter.

“…In applications that require a step-down of the input voltage, buck-type topologies are the first choice due to their compact size and ability to handle varying loads [ 1 , 2 ]. They are commonly used in various electronic devices and applications where efficient power converters are necessary, like power supplies [ 3 , 4 ], battery charging [ 5 , 6 , 7 , 8 , 9 , 10 , 11 ], IoT applications [ 12 , 13 ], LED drivers [ 14 , 15 , 16 ] and renewable energy [ 17 ].…”

The paper introduces a step-down converter that exhibits a static conversion ratio of cubic nature, providing an output voltage which is much closer to the input voltage, and at the same duty cycle, compared to a wide class of one-transistor buck-type topologies. Although the proposed topology contains many components, its control is still simple, as it employs only one transistor. A dc analysis is performed, the semiconductor stresses are derived in terms of input and output voltages and output power, revealing that the semiconductor voltage stresses remain acceptable and anyway lower than in other cubic buck topology. All detailed design equations are provided. The state-space approach is used to analyze the converter in the presence of conduction losses and a procedure for calculating the individual power dissipation is provided. The feasibility of the proposed cubic buck topology is first validated by computer simulation and finally confirmed by an experimental 12 V–10 W prototype.
