Q:Three-phase photovoltaic inverter grid, the use of phase-locked loop is what?
In addition to the function of converting DC current into alternating current, the inverter also has the maximum output tracking function (MPPT), overvoltage protection, short circuit protection, island protection, overheat protection, overload protection and DC grounding
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:PV grid-connected inverter can directly load it?
TL5001 operating voltage range of 3.6 ~ 40V, its internal with an error amplifier, a regulator, oscillator, a dead zone control PWM generator, low voltage protection circuit and short circuit protection circuit
Q:Grid-connected inverter is generally divided into photovoltaic power generation grid-connected inverter, wind power grid-connected inverter, power equipment and grid-connected inverter and other power generation equipment power generation inverter.
The small use of field-effect transistors while using a DSP conversion controller to improve the quality of the output power makes it very close to the sine wave current.
Q:How the output voltage of the PV inverter and the grid-connected voltage are determined
supply through the cable to the battery. The use of household appliances connected to the power converter output can be used in the car a variety of electrical appliances. The available electrical appliances are: mobile phones, laptops, digital cameras, cameras, lights, electric razors, CD players, game consoles, handheld computers, power tools, car refrigerators and various tourism, camping, medical emergency appliances Wait.
Q:What are the methods of photovoltaic grid-connected inverter control
Inverter main circuit need to have a control circuit to achieve, generally have square wave and sine wave two control methods, square wave output inverter power supply circuit is simple, low cost, but low efficiency, harmonic components. Sine wave output is the development trend of the inverter, with the development of microelectronics technology, there are PWM function of the microprocessor has also come out, so the sine wave output inverter technology has matured.
Q:The function of photovoltaic grid - connected inverter
After some additional voltage buffering, the left side of the bridge is usually 18 ~ 20khz switching frequency, the dc voltage is converted to ac voltage.
Q:What is the difference between a PV grid-connected inverter and an off-grid inverter?
Grid-connected inverter will be directly sent to the power grid, so to track the frequency of the grid, phase, the equivalent of a current source. Of course, there are some inverters called low-voltage crossing ability, you can do PQ adjustment
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:In a photovoltaic grid-connected project, the role of the inverter is to convert the voltage into AC 220V or 380V for the grid, since the transformer will raise the voltage again
Part of the distributed grid-connected projects, the basic are "spontaneous use, the power of the Internet," these do not need to boost, because the extra power is actually consumed by the surrounding electricity users, do not boost to a Level power grid;
