Title:
BRAKE CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/153769
Kind Code:
A1
Abstract:
The present invention improves the power generation efficiency of a power generating system. A first switch (Sw1) and a first resistor (R1) are connected in series between a first power line (Pu) and a second power line (Pv). A second switch (Sw2) and a second resistor (R2) are connected in series between the second power line (Pv) and a third power line (Pw). A third switch (Sw3) and a third resistor (R3) are connected in series between the third power line (Pw) and the first power line (Pu). If a brake condition indicating that an abnormality has occurred in the electricity generating system is established, a control unit (52) switches the states of each of the first switch (Sw1), the second switch (Sw2) and the third switch (Sw3) between a non-conducting state and a conducting state, on the basis of a duty ratio corresponding to the rotational speed of an electric power generator (3). The duty ratio is smaller the greater the rotational speed of the electric power generator (3).
