Briefly Introduction about the difference between soft starter and inverter

UpdateTime:2013-01-24Clicks:1395Word Size:T|T

Soft start is a set of novel motor soft start, soft stop, and a variety of energy-saving light-load

protection functions in one of the novel motor control device, called Soft Starter abroad. Its main

components are connected in series between the power supply and charged three thyristors in

parallel and opposite to the electronic control circuit between the motor. Use different methods to

control the three opposite parallel thyristor conduction angle, to make the accused motor input voltage

varies according to different requirements, different functions can be achieved.

Soft starters and frequency converters are two completely different uses of the product. Frequency

converter is where used in the need for speed regulation, the output is not only changing the voltage

but also changing the frequency; soft starter is actually a regulator for motor starting, the output

voltage does not change just to change the frequency. Frequency converter has all the soft starter

function, but its price is much more expensive than the soft starter, the structure is much more

complex.

Soft start is just changing the power supply voltage, the equivalent of step-down starter. Frequency

converter is much more complex than the soft starter, the price is much more expensive. Frequency

converter also has a soft start function which is achieved by changing the power frequency.
