In the present embodiment, predetermined control rule is：In 2j current sensor 15, if a current feedback signal connects
It is zero and when other current feedback signals are all non-zero to continue, and controller is judged as corresponding driver element 191, bridge arm unit
2011st, brush or armature winding branch road 1121 break down, and the output operation control signal 17 of controller 16 causes corresponding driving
Unit 191 enters halted state；If a current feedback signal is continuously more than the 1.5 of other current feedback signal average values
When more than times, controller 16 judges corresponding bridge arm unit 2011 or armature winding branch road 1121 for short trouble, controller 16
Output operation control signal 17 cause corresponding driver element 191 enter halted state so that by the corresponding driver element of failure,
Bridge arm unit, brush and armature winding branch road carry out shielding isolation, it is to avoid the further expansion of failure.
The effect of embodiment and effect
The Vidacare corp and electrical equipment provided according to the present embodiment, driver contain 2j it is separate and
Parameter identical driver element, direct current generator have 2j armature winding branch roads that are separate and being made up of m winding and
2j × m commutator segment of winding connection, it is located at the both sides of armature winding branch road and 2 groups of brushes being in contact with commutator segment respectively
Group, each brush group includes j separate brushes, and chopper has 2 bridge arms corresponding with 2 groups of brush group difference
Portion, each bridge arm portion includes the j bridge arm units connected one to one with j brush of corresponding brush group, therefore each bridge arm
The line current of any two bridge arm unit output in portion is separate, non-interfering, and then causes the output electricity of chopper
Stream can linearly be increased by increasing the number of bridge arm unit, and infinity can be reached in theory.Not only remain and cut originally
The ripe control algolithm and the mature technology of direct current generator of ripple device, and reduce power switch pipe consistency of performance is wanted
Ask, the requirement of high current can be met using common power switch pipe, it is to avoid essence is chosen carefully from substantial amounts of power switch pipe
The consuming for a large amount of manpower and financial resources that the switch element for selecting uniformity high is brought.
Each driver element correspondence is connected to a bridge arm unit, a brush and two armature winding branch roads, when appoint
When one driver element of meaning, bridge arm unit, brush or armature winding branch road produce failure, the fault-tolerant dress of motorized motions of the present embodiment
Put and driver element, bridge arm that current value that electrical equipment is detected by calculating current sensor and judging breaks down
After unit, brush or armature winding branch road, controller output operation control signal makes corresponding driver element be stopped, so that
The driver element of damage, bridge arm unit, brush or armature winding branch road are subjected to shielding isolation, it is to avoid the further expansion of failure
Greatly, it is ensured that Vidacare corp and electrical equipment can continue normal work or light running, and electronic set has been dramatically reduced
The probability that standby, particularly high-speed cruising electrical equipment security incident occurs.
In addition, the Vidacare corp of the present embodiment can break the external monopolization for great current drive device and envelope
Lock so that the direct current drive drive device can not only replace the fuel oil hair that pollution is big, toggle speed is slow and energy utilization rate is low
Motivation and applied at present can not using motor heavy-duty engine on, such as truck, bull-dozer, excavator heavy-duty engine etc.,
It can also be applied to need in military affairs on the electronic battlebus, electronic warship and electric drive aircraft carrier of more high current, realize low
Press the production domesticization of the Vidacare corp of high current.And compared with AC motor drives, systematic function is more superior.

Performance is stable, safe and reliable, the advantages of service life is long.
In the above-described embodiments, brush is narrow brush, but brush or wide brush as the present invention.
In addition, dc source is the rectification source obtained after battery pack or the rectified filtering of AC power, dc source is one
Individual entirety connects one to one and separate power subsystem with 2j with 2j bridge arm unit.When dc source has
During 2j separate power subsystems, the output current of each power subsystem is smaller for dc source total current,
The connector of the connector of connecting line, connecting line and power subsystem between power subsystem and chopper, connecting line and chopper,
Requirement to contact resistance and insulation is relatively low, not only reduces the difficulty and cost of production, also contributes to the reliable of system
Property and security.
When power subsystem is battery pack and during with the separate battery units of 2j, the battery cell in battery unit
Parallel technology can not be needed, requirement can be met only with serial connection technology, eliminates what is produced after multiple battery cells parallel connections
Battery balanced problem, also eliminates to reduce the expense that the inconsistency of multiple battery cells is produced.In terms of power supply, by many
Individual relatively small capacity series-connected cell unit instead of the connection in series-parallel battery pack of single Large Copacity, identical in battery cell quantity
In the case of, battery is reduced because overall performance caused by parallel connection is decayed, and improves energy density, power, performance, durability
And security, continuation of the journey and performance that can be for electrical equipment provide more preferable guarantee.
General principle, principal character and the advantages of the present invention of the present invention has been shown and described above.The technology of the industry
Personnel are it should be appreciated that the present invention is not limited to the above embodiments, and the simply explanation described in above-described embodiment and specification is originally
The principle of invention, without departing from the spirit and scope of the present invention, various changes and modifications of the present invention are possible, these changes
Change and improvement all fall within the protetion scope of the claimed invention.
