2) self-commutated converter;

3) chopper;

4) Inverter;

b) indirect converter;

c) rolling stock and more supply converter.

1.3 Technical Information

1.2 The converter contains the following aspects.

a) species;

b) the circuit structure and basic properties;

c) the basic parameters;

d) control mode;
