Abstract
The invention relates to a power module (9) for converting an electric current flowing between an accumulator and an alternating-current motor, said module (9) comprising switching means (10) that can be controlled to authorize the powering of the motor and/or the charging of the accumulator, and an intrinsic control unit (13) connected to said switching means (10) and capable of delivering opening and/or closing signals to said switching means (10), said intrinsic control unit (13) being further capable of exchanging data with a remote control unit, with a potential barrier.
Claims19
An individual power module that converts an electric current flowing between an accumulator and an alternating-current motor, said module comprising:
- a plurality of switches that are controlled to authorize the powering of the motor and enable the charging of the accumulator;
- and
- a digital processor connected to the plurality of switches to deliver opening and closing signals to the plurality of switches, and to exchange data with a remote control unit,
- wherein the exchange of data is made across a galvanic isolation barrier,
- said plurality of switches comprising:
- at least one arm formed from two switches, assembled in series, controlled from said digital processor, and,
- means for driving the plurality of switches linked up to said digital processor and the plurality of switches, said driving means being able to supply a current for closing and/or opening the plurality of switches from the opening and/or closing signals of said digital processor.
A voltage converter comprising:
- at least one individual power module comprising:
- a plurality of switches that are able to power the motor and enable the charging of the accumulator;
- and
- a digital processor connected to the plurality of switches to deliver opening and closing signals to the plurality of switches, and to exchange data with a remote control unit,
- wherein the exchange of data is made across a galvanic isolation barrier,
- said plurality of switches comprising:
- at least one arm formed from two switches, assembled in series, controlled from said digital processor, and,
- means for driving the plurality of switches linked up to said digital processor and the plurality of switches, said driving means being able to supply a current for closing and/or opening the plurality of switches from the opening and/or closing signals of said digital processor;
- and
- a remote control unit that exchanges data with the digital processor of the module across the galvanic isolation barrier.
An electric device for combined powering and charging, comprising:
- an alternating-current motor;
- an accumulator;
- an inverter for the combined powering of the alternating-current motor and the charging of the accumulator said inverter being equipped with at least one individual power module comprising:
- a plurality of switches that are able to power the motor and enable the charging of the accumulator;
- and
- a digital control unit connected to the plurality of switches to deliver opening and closing signals to the plurality of switches, and to exchange data with a remote control unit,
- wherein the exchange of data is made across a galvanic isolation barrier;
- a remote control unit, able to exchange data with the digital control unit of the power module or modules to handle the switch from the powering mode to the changing mode.
A method to implement an electric device that combines the powering and charging, comprising an alternating-current motor, an inverter for the combined powering of the alternating-current motor and the charging of the accumulator said inverter being equipped with at least one individual power module that comprises a plurality of switches that are able to power the motor and enable the charging of the accumulator, and a digital control unit connected to the plurality of switches to deliver opening and closing signals to the plurality of switches, and to exchange data with a remote control unit, the exchange of data is made across a galvanic isolation barrier, the electric device further comprises a remote control unit that exchanges data with the digital control unit of the power module or modules to handle the switch from the powering mode to the charging mode, a DC/DC converter comprising the at least one individual power module, the DC/DC converter being arranged between the accumulator and the inverter, the method comprising:
- superimposing a plurality of electronic layers, the layers being such that:
- a first layer forms the inverter,
- a second layer forms the remote control unit, and
- a third layer forms the DC/DC converter.
