Q:Is the PV inverter a current source or a voltage source?
The inverter is mainly composed of a switching element such as a transistor, and turns the DC input into an AC output by repeatedly turning ON-OFF the switching element in a regular manner.
Q:PV grid-connected inverter and independent inverter in the control of what is the difference
The independent inverter in the output voltage phase amplitude of the frequency control is initially set good. Independent inverter, you should refer to off-grid inverter, do not need to consider the grid situation.
Q:The working principle of photovoltaic grid - connected inverter
Full-bridge inverter circuit to overcome the shortcomings of the push-pull circuit, the power transistor to adjust the output pulse width, the output AC voltage RMS that changes. Since the circuit has a freewheeling circuit, even if the inductive load, the output voltage waveform will not be distorted. The disadvantage of this circuit is that the upper and lower arms of the power transistor are not common, so you must use a special drive circuit or use isolated power supply. In addition, in order to prevent the upper and lower arm co-conduction, must be designed to turn off after the conduction circuit, that must be set dead time, the circuit structure is more complex.
Q:Photovoltaic grid-connected inverter problem
But Baidu Encyclopedia clearly pointed out: the zero line is the secondary side of the transformer leads the neutral point of the line, and the phase line constitutes a circuit for power supply equipment.
Q:What is the difference between low voltage grid connection and medium voltage grid connection?
Have a low pressure through the function set, low pressure through the scope of the project requirements, grid and network requirements and the actual situation of the design), low voltage grid to pass the voltage range is less than the medium pressure, parameter settings are not sensitive and complex.
Q:After the PV inverter, how to achieve the same period before the network?
Grid simulator: analog power grid, normal and abnormal conditions, overvoltage, undervoltage, over frequency, under frequency, sudden power failure, etc.
Q:What are the methods of photovoltaic grid-connected inverter control
Sine wave output inverter control integrated circuits, sine wave output of the inverter, the control circuit can be used microprocessor control, such as INTEL company produced 80C196MC, Motorola produced MP16 and MI-CROCHIP company PIC16C73 and so on, these single-chip microcomputer has a multi-channel PWM generator,
Q:The function of photovoltaic grid - connected inverter
By dc / dc conversion to increase or decrease the input voltage, adjust its output to achieve maximum efficiency.
Q:Photovoltaic grid-connected inverter without DC emc how will happen
Solar photovoltaic power generation technology is the use of solar cells, the photovoltaic effect of semiconductor materials, solar radiation can be directly converted into a new type of power generation system, solar energy is a radiant energy, solar power means --- to direct conversion of sunlight Into electricity,
Q:What is the difference between a grid-connected inverter and an off-grid inverter? What are the advantages of a hybrid inverter?
Off-grid inverter is equivalent to their own to establish an independent small power grid, mainly to control their own voltage, is a voltage source.
