1, Product desciption
Inverter circuits designed to produce a variable output voltage range are often used within motor speed controllers.
The DC power for the inverter section can be derived from a normal AC wall outlet or some other source. Control and feedback circuitry is used to adjust the final output of the inverter section which will ultimately determine the speed of the motor operating under its mechanical load.
Motor speed control needs are numerous and include things like: industrial motor driven equipment, electric vehicles, rail transport systems, and power tools. (See related: variable-frequency drive ) Switching states are developed for positive, negative and zero voltages as per the patterns given in the switching Table.
The generated gate pulses are given to each switch in accordance with the developed pattern and thus the output is obtained.
2, Features of the product
Inverters convert low frequency main AC power to higher frequency for use in induction heating.
To do this, AC power is first rectified to provide DC power. The inverter then changes the DC power to high frequency AC power. Due to the reduction in the number of DC Sources employed, the structure becomes more reliable and the output voltage has higher resolution due to an increase in the number of steps so that the reference sinusoidal voltage can be better achieved.
This configuration has recently become very popular in AC power supply and adjustable speed drive applications. This new inverter can avoid extra clamping diodes or voltage balancing capacitors. There are three kinds of level shifted modulation techniques, namely:Solar power is energy from the sun and without its presence all life on earth would end. Solar energy has been looked upon as a serious source of energy for many years because of the vast amounts of energy that are made freely available, if harnessed by modern technology.
A simple example of the power of the sun can be seen by using a magnifying glass to focus the suns rays on a piece of paper. Before long the paper ignites into flames.
Is the electrical grid already nearby or would you need to call in the power company to bring in electrical lines.
If the electric needs to be brought to the area, how much is this going to cost? Depending on how far the grid electric is from the location of the needed lighting, this can be quite expensive.
How much lighting is needed on the street? Do the lights need to be dark sky compliant.
Do the street lights need to run from dusk to dawn or for only a specified number of hours at night.
Are the street lights able to dim in the middle of the night and still provide enough lighting.
These questions need to be answered before you can decide on how many lights you will need to complete the project.
