1. 1. The primary input voltage can be increased. If the secondary output voltage remains unchanged, the primary input voltage should be increased three times
2. The secondary output voltage can be increased. If the primary output voltage remains unchanged, the secondary output voltage should be increased by three times.

There is no electrical connection between primary winding and secondary winding of isolation transformer, that is, the two windings are not connected to each other; The primary winding of the autotransformer is connected with the synonym of the secondary winding by a line
3. Transformer primary series, secondary can parallel:
transformer primary series: for example: two 110V transformer primary series after the 'primary' can be used for 220V voltage
can the secondary be connected in parallel: for example, after two 110V transformers are connected in series, the "primary" can be used for 220V voltage. As like as two peas, the secondary voltage can run in parallel. Otherwise, the opposite is true.
