Problems solved by technology
[0003] To charge different electric vehicles, due to the different battery pressures, when multiple power sources are connected in parallel, the charging pile needs to adjust the voltage to be consistent. The duty cycle realizes voltage regulation, and the pulse accuracy depends on the pulse width. When the pulse frequency is higher, the component size is smaller, and the equipment cost is lower, but the accuracy is more difficult to adjust; when the pulse frequency is lower, the component size is smaller. Large, although the accuracy is easy to adjust, but the equipment cost is higher

The application discloses a voltage regulation control circuit, system and method, wherein the voltage regulation control circuit includes: after the micro control unit outputs the voltage pulse signal, by setting a capacitor array and a triode in series to ground, when the triode is disconnected, the capacitor The array is in a floating state. When the triode is turned on, the capacitor array can be grounded, and the output energy can be poured into the ground terminal to realize energy subtraction. The output voltage pulse signal can be changed from a square wave waveform to a sine waveform, and the area of the waveform changes, resulting in a change in the output voltage, thereby achieving precise regulation of the voltage value on the premise of reducing equipment costs. A pressure regulating control system and method disclosed in the present application also have corresponding technical effects.
Description
technical field [0001] The invention relates to the technical field of electrical voltage regulation, in particular to a voltage regulation control circuit, system and method. Background technique [0002] With the increasing awareness of global energy saving and environmental protection, the electric vehicle industry in the field of new energy is developing rapidly. With the country's vigorous promotion of electric vehicles, the use of electric vehicles is growing rapidly, resulting in a gradual increase in the demand for charging piles on the market. [0003] To charge different electric vehicles, due to the different battery pressures, when multiple power sources are connected in parallel, the charging pile needs to adjust the voltage to be consistent. The duty cycle realizes voltage regulation, and the pulse accuracy depends on the pulse width. When the pulse frequency is higher, the component size is smaller, and the equipment cost is lower, but the accuracy is more di...
