Since the birth of artificial intelligence, theories and technologies become mature day by day, and application fields are expanded continuously, so that science and technology products brought by the artificial intelligence in the future can be assumed to be 'containers' of human intelligence. The artificial intelligence can simulate the information process of human consciousness and thinking. Artificial intelligence is not human intelligence, but can think like a human, and can also exceed human intelligence.
The world is replete with smart phones, smart cars and smart appliances, and speech plays an important role in these devices. The voice recognition enables the smart home to absorb prompts and pronunciations, and forms a mode and smart home connection according to a human communication mode. The working principle of the voice recognition technology is as follows: the user speaks words by invoking speech recognition on the mobile application, and the spoken words are processed by the recognition software and converted to text. The converted text is then provided as input to a search mechanism, which returns results.
In modern scientific research and industrial production, the numerical control direct current source with high precision and good stability is widely applied. Most of the current sources used in the past are adjusted by potentiometers, and the output current value cannot realize accurate stepping. Although some current sources can realize numerical control, the output current value is often too small, and whether the set output current value is accurate or not cannot be determined without testing, so that the current sources are not intuitive.
The adjusting tube in the linear direct current voltage-stabilizing current source works in a linear state, the ripple of the linear voltage-stabilizing current source is small, the reflecting speed is high, and the noise generated by the work is low. Because the adjusting tube is equivalent to a resistor, the current generates heat through the resistor, and because the adjusting tube works in a linear state, a large amount of heat is generally generated, so that the efficiency is not high, which is also a defect of a linear voltage stabilizing source.
In order to obtain adjustable direct current, the complete controllability of an electronic device is utilized, a pulse width modulation technology is adopted, constant direct current voltage is directly modulated into direct current voltage with variable size and polarity, and the adjustable direct current voltage is converted into adjustable direct current at an output end.
PWM modulated switching power supplies have relatively severe switching disturbances that can seriously affect the operation of the power supply if these disturbances are not suppressed, eliminated and masked by certain measures. As the domestic microelectronic technology has certain gap with some advanced countries, the cost is higher and the reliability is influenced. Even in the state with advanced technology, although the switching regulator has a certain development, in practical application, some problems still exist, such as complex circuit structure, high failure rate and troublesome maintenance, which directly affect the popularization and application of the switching regulator.
At present, the voltage source power supply mode is mainly used, but the voltage source power supply mode has the defect that the change of voltage or load is detected by using output voltage and then corrected by using a feedback system, and the speed response is slow. Compensation is further complicated by the fact that the loop gain of the circuit changes with changes in the input voltage, and current mode control alleviates all of these disadvantages.
