The zero line of the zero line and inverter of stating extraneous power supply is connected.During use, when extraneous power supply can pass through diode, electric current is positive
By the normal open switch of relay, when extraneous power supply can not by diode when, electric current back through the normally closed switch of relay,
This just by the alternating current of both direction, becomes the unidirectional current in a direction.Using the commutator of this structure, except controlling side
Beyond one diode, do not adopt other electronic original part, and this controls the diode of side not over larger electric current, because
Even if this is in the case of high power, loss is not very big.
In technique scheme it is preferred that be provided between the other end of described relay switch and described zero line for
The electric capacity of filtering.
Compared with prior art, the beneficial effects of the utility model are：The when unidirectional current that commutator input comes, that is,
The polarity saying electricity on input brush is all fixing, but conducting block is ceaselessly rotating along motor, so conducting block can be with
Different input brushes contacts, and leads to can derive alternating current on output brush.Adopt inverter in this way, do not have completely
Use electronic device, whole losses is exactly only line loss and the loss of motor, so substantially increasing Energy Efficiency Ratio.
