Title: Regenerative control circuit of dc separately exited shunt motor and its regenerative control method
Inventor: OKAZAKI SUMIOMI
IPC: H02P7/298
Filed: 2000-02-07
Abstract: PROBLEM TO BE SOLVED: To prevent breakdown of a switching element by a method, where a regenerative current and a field current flow according to a command and brake torque is constant, while a battery current is not decreased, and an excessive regenerative current is restrained, when the battery voltage is decreased. SOLUTION: When the battery voltage is not decreased, the regenerative current and the field current are ensured according to the command, and the brake torque is controlled to be constant as normal. When the battery voltage is decreased, an overcurrent flows in a current flowing element 8 for first DUTY control, even if other switching elements are turned off, in normal case. By performing control in such a manner that DUTY of a current flowing element 7 for second DUTY control is decreased, the overcurrent flowing in the element 8 is restrained and breakdown of the element 8 can be prevented. The current flowing element for the first DUTY control is an IGBT, which is apt to be broken down by an overcurrent.
