400 Hz was first chosen for aircraft design as it ensured a more compact design (and hence lighter weight) for the electrical systems. Generators providing 400 Hz power use less copper in their windings and smaller magnetic cores than those of 50 or 60 Hz - making them lighter.

Inverters play a crucial role in any solar energy system and are often considered to be the brains of a project, whether it's a 1-kW residential system or a 2-MW utility power plant. An inverter's basic function is to [invert" the direct current (DC) output into alternating current (AC).

1 use current transformer to detect over-current for protection The current transformer is connected in series with IGBT to detect the current flowing through the IGBT collector. When over-current occurs, the control actuator disconnects the IGBT input. 2.VCE (SAT) of IGBT detects over-current for protection Because VCE (SAT) = icrce (SAT), when IC increases, VCE (SAT) also increases. If the gate voltage is high and VCE is high, there will be over-current. At this time, the gate outputs high level, and the over-current signal is output. The actuator is controlled to disconnect the input of IGBT to protect IGBT. 3. Detect the load current for protection If the load is short circuited or the load current increases, the collector current of the former IGBT may also increase, resulting in IGBT damage. After the load (or the next stage circuit of IGBT) detects the abnormality, the control actuator cuts off the input of IGBT.

1.confirm what is the total capacit of the load. 2. Study the type specifications and main parameters of the frequency converter. a. Converter rated voltage: 220V, 380V, 660V, 690V, etc. Converter rated frequency 50hz 60hz or 400hz. b.Converter is the maximum power when the inverter runs, and sometimes the number of converters is increased according to the load and the use environment. c. rated current: the maximum working current when the Converter runs, and the current of the Converter must be greater than the rated current of the motor. d. Converter overload capacity: fan, water pump inverter overload 120%, universal overload 150%;

A power inverter, or inverter, is a power electronic device or circuitry that changes direct current (DC) to alternating current (AC). The input voltage, output voltage and frequency, and overall power handling depend on the design of the specific device or circuitry.

Induction motors turn at a speed proportional to frequency, so a high frequency power supply allows more power to be obtained for the same motor volume and mass. Transformers and motors for 400 Hz are much smaller and lighter than at 50 and 60 Hz, which is an advantage in aircraft .

Simply put, frequency converters are a power conversion device. The frequency converter converts a basic fixed-frequency, fixed voltage sine-wave power (line power) to a variable-frequency, variable-voltage output used to control speed of induction motors.

A frequency inverter is often confused with a frequency converter since both appear to change frequency and amperage. ... The primary difference is frequency inverter only change frequency,but the frequency converter is change voltage and frequency.

The present invention relates to a method and apparatus for power generation, and in particular a method and apparatus for the control of electrical power generation for use primarily with wind turbines. A method of electrical power generation is described including the steps of: receiving power in the form of alternating current; rectifying said alternating current power to direct current power; control said direct current power to produce controlled direct current power; and inverting said near constant direct current power to produce alternating current.

Sine wave inverter, modified wave inverter, power frequency inverter. The inverter is to convert the DC power (battery, storage battery) into the transaction current (generally 220V, 50Hz sine wave). At present, inverter is widely used in air conditioning, home theater, electric grinding wheel, electric tools, sewing machine, DVD, VCD, computer, TV, washing machine, range hood, refrigerator, video recorder, massager, fan, lighting, etc. What are the specific types? The output of sine wave inverter is the same or better sine wave AC as the grid we use everyday, because there is no electromagnetic pollution in the grid. The output of square wave inverter is square wave alternating current with poor quality. The maximum value of its positive direction to the maximum value of its negative direction is almost generated at the same time, which has a dramatic unstable impact on the load and the inverter itself. At the same time, its load capacity is poor, only 40-60% of the rated load, without inductive load. If the load is too large, the third harmonic component in the square wave current will increase the capacitive current flowing into the load, and even damage the power filter capacitance of the load. In view of the above shortcomings, quasi sine wave (or modified sine wave, modified sine wave, analog sine wave and so on) inverter appears. Its output waveform has a time interval from the positive maximum value to the negative maximum value, and the use effect is improved. However, the quasi sine wave waveform is still composed of broken lines, belonging to the category of square wave, with poor continuity. Generally speaking, sine wave inverter provides high-quality alternating current and can drive any kind of load, but its technical requirements and cost are high. Quasi sine wave inverter can meet most of our power demand, high efficiency, low noise, moderate price, so it becomes the mainstream product in the market. The square wave inverter is made of simple multivibrator, whose technology belongs to the level of the 1950s, and will gradually withdraw from the market. According to the different power supply, the inverter is divided into coal power inverter, solar power inverter, wind power inverter and nuclear power inverter. According to different purposes, it is divided into independent control inverter and grid connected inverter.

Wind turbines work on a very simple principle: the wind turns the blades, which causes the axis to rotate, which is attached to a generator, which produces DC electricity, which is then converted to AC via an inverter that can then be passed on to power your home.
