Electric load apparatus, method for processing abnormality, and computer readable recording medium recording program for causing computer to execute processing of abnormality in electric load apparatus
View Patent ↗Control apparatus ( 30 ) forcefully stops inverter ( 14 ) and inverter ( 31 ) when DC/DC converter ( 12 ) is anomalously stopped. Additionally, when one of inverters ( 14, 31 ) is anomalously stopped while DC/DC converter ( 12 ) is normal, control apparatus ( 30 ) forcefully stops the other inverter. Then, when a recovery condition is satisfied after the other inverter is forcefully stopped, control apparatus ( 30 ) recovers the other inverter.
1. An electric load apparatus, comprising:
a voltage converter converting a first DC voltage output from a DC power source to a second DC voltage that is different in voltage level from said first DC voltage;
first and second electric loads driven by said second DC voltage;
a capacitive element smoothing said second DC voltage and supplying the smoothed second DC voltage to said first and second electric loads; and
an abnormality processing unit, when an abnormality occurs in one of said first and second electric loads, the abnormality processing unit stopping the other of said first and second electric loads and permitting said voltage converter to continue operating.
2. The electric load apparatus according to claim 1 , wherein
when an abnormality occurs in said voltage converter, said an abnormality processing unit stops said first and second electric loads.
3. The electric load apparatus according to claim 1 , wherein
when a recovery condition is satisfied, said abnormality processing unit permits said other of the electric loads to operate.
4. The electric load apparatus according to claim 1 , wherein
said first electric load includes
a motor and
a first inverter driving said motor, and
said second electric load includes
a generator and

5. A computer readable recording medium recording a program for causing a computer to execute processing of an abnormality in an electric load apparatus; wherein
said electric load apparatus includes
a voltage converter converting a first DC voltage output from a DC power source to a second DC voltage that is different in voltage level from said first DC voltage,
first and second electric loads driven by said second DC voltage, and
a capacitive element smoothing said second DC voltage and supplying the smoothed second DC voltage to said first and second electric loads, and wherein
said program causes the computer to execute
a first step of detecting an abnormality in any of said voltage converter, said first electric load and said second electric load, and
a second step of stopping the other of said first and second electric loads, when an abnormality occurs in one of said first and second electric loads, and permitting said voltage converter to continue operating.
6. The computer readable recording medium recording a program for causing a computer to execute according to claim 5 , wherein
said first step detects an abnormality of said voltage converter, and
said second step stops said first and second electric loads.
7. The computer readable recording medium recording a program for causing a computer to execute according to claim 5 , wherein
said program further causes the computer to execute a third step of permitting said other of the electric loads to operate when a recovery condition is satisfied.
8. The computer readable recording medium recording a program for causing a computer to execute according to claim 5 , wherein
said first electric load includes
a motor and
a first inverter driving said motor, and
said second electric load includes
a generator and
a second inverter driving said generator.
9. A method for processing an abnormality in an electric load apparatus, wherein
said electric load apparatus includes:
a voltage converter converting a first DC voltage output from a DC power source to a second DC voltage that is different in voltage level from said first DC voltage,

a capacitive element smoothing said second DC voltage and supplying the smoothed second DC voltage to said first and second electric loads, and wherein
said method for processing an abnormality includes:
a first step of detecting an abnormality in any of said voltage converter, said first electric load and said second electric load, and
a second step of stopping the other of said first and second electric loads, when an abnormality occurs in one of said first and second electric loads, and permitting said voltage converter to continue operating.
10. The method for processing an abnormality according to claim 9 , wherein
said first step detects an abnormality of said voltage converter, and
said second step stops said first and second electric loads.
11. The method for processing an abnormality according to claim 9 , further comprising
a third step of permitting said other of the electric loads to operate when a recovery condition is satisfied.
12. The method for processing an abnormality according to claim 9 , wherein
said first electric load includes
a motor and
a first inverter driving said motor, and
said second electric load includes
a generator and
a second inverter driving said generator.
