摘要： A brake control device for an electric vehicle includes an instruction controller, a pattern generator, and comparators. The instruction controller generates an instruction signal for instructing a motor about electric brake force. The pattern generator generates a first pattern signal for changing over electric brake force to machine brake force and a second pattern signal obtained by shifting the first pattern signal by a predetermined frequency. One of the comparators outputs, as an electric-brake force pattern, smaller one of the instruction signal and the first pattern signal. The other of the comparators outputs, as a notification signal, a signal output when the second pattern signal becomes equal to or smaller than the instruction signal.

摘要： A controller (2), when activating a power converter (1), outputs a gate signal to close a switch (SW1) for a set conduction time, and while the power converter (1) is active, outputs a gate signal to alternately close switches (SW1, SW2) for the conduction time. The controller (2), when stopping the power converter (1), outputs a gate signal to open the switches (SW1, SW2) after the switch (SW2) that was not closed upon the activation is closed for the conduction time without closing the switch (SW1) that was closed upon the activation.
