By way of comparison, AC harmonic filters of typical line-commutated converter stations cover nearly half of the converter station area.
22.
For this reason, a line commutated converter for HVDC is also considered as a " current-source inverter ".

24.
Active crowbars use a transistor, gate turn off ( GTO ) thyristor or forced commutated thyristor instead of a thyristor to short the circuit.
25.
A synchronous motor was chosen over a commutated motor or an asynchronous motor due to the reduced mass, simplicity of equipment, and price.
26.
Genteq develops and manufactures electronically commutated motors ( ECM ) and capacitors for residential and light commercial heating and air conditioning ( HVAC ) systems.
27.
Line-commutated converters ( LCC ) used mercury-arc valves until the 1970s, or thyristors from the 1970s to the present day.
28.
In HVDC applications, the AC power system itself provides the means of " commutating " the current to another valve in the converter.
29.
In a line-commutated converter, the DC current does not change direction; it flows through a large inductance and can be considered almost constant.
30.
However, his sentences were commutated, happening some years in prison; in some cases, went back to occupy public charges after serving the sentence.
