Stepped wave Inverter is simple but has lower order harmonics which cannot be eliminated by filters.These harmonics can be eliminated by the Space Vector PWM technique.
In the space vector PWM technique, there is 15% increment in maximum voltage compared to PWM, hence Space Vector enables efficient use of DC voltage.Space Vector Modulation provides excellent output performance, optimized efficiency and high reliability compared to similar Inverters with conventional PWM
What else can I help you with?
What happen when you remove braking resistor on the inverter?
The system will lose it's regenerative braking function, if there is no other means to stop the motor it will coast to a stop.
Difference between inverter and pwm control?
One invert the function or a signal. the other is a pulse width modulator controller which are usually used to convert one source of power to another. As in 12v dc in 5v dc out or vice versa
What is the advantages and disadvantages of substation busbar?
There are no particular disadvantages for busbars, other than they must be insulated and occupy space, but as busbars are essential, then this is to be expected.
Describe the advantages of using a parallel arrangement of decorative lights rather than a series arrangement?
The advantages of parallel arrangement decorative lights are:More brightnessWhen one light bulb blows out, the other ones do notLast much longer than series lights
Why is identification of the vector group of transformer important?
Vector group means it defines the primary & secondary side connection type of the transformer.For example DY says D for the delta connections (windings connected between two phases) & Y for the star connections (windings connected between two phases). That's why identification of the vector group of transformer is important.AnswerVector groups specify whether two or more three-phase transformers can be paralleled with each other. In order to do so, their angular displacements must be the same. Transformer connections listed in the Vector Group tables, categorise transformer connections in terms of their angular displacements.
How do you find missing vector if resultant is given?
The Resultant Vector minus the other vector
What are other names for NOT gate?
Another name is an Inverter.
Find a vector that is not in the range of r3?
R3 is a complete vector room, so you can actually take *ANY* other vector, e.g. from r1, r2 or r4 or any other vector room.
What the difference between vector and resultant vector?
Equilibrant vector is the opposite of resultant vector, they act in opposite directions to balance each other.
How single EX-OR gate can be used as inverter?
tie one input to permanent 1 level, use other input as inverter input.
A vector that respersents the sum of two or more other vectors is the?
A resutant vector
What is a vector which is orthogonal to the other vectors and is coplanar with the other vectors called?
In a plane, each vector has only one orthogonal vector (well, two, if you count the negative of one of them). Are you sure you don't mean the normal vector which is orthogonal but outside the plane (in fact, orthogonal to the plane itself)?
What does a vector equal?
Any other vector with with the same magnitude and the same direction.
What is meant by resultant of a vector?
A resultant vector is one vector which can replace all the other vectors and produce the same effect.
What is the difference between resultant and equilibrant vector?
A resultant vector is the single vector that represents the combined effect of multiple vectors. It is obtained by adding together all the individual vectors. An equilibrant vector is a single vector that, when added to the other vectors in the system, produces a net result of zero, effectively balancing out the other vectors.
Is vector A parallel vector B given that vector A is equal to the zero vector and vector B is equal to the zero vector?
The zero vector is both parallel and perpendicular to any other vector. V.0 = 0 means zero vector is perpendicular to V and Vx0 = 0 means zero vector is parallel to V.
What is a perpendicular vector?
A perpendicular vector is a vector that forms a right angle (90 degrees) with another vector in a given space. This means that the dot product of two perpendicular vectors is zero, indicating that they are orthogonal to each other.
