<p>Disclosed herein is an over-current damage prevention method and apparatus for a subsidiary inverter of an electric bus, which may reduce surge current generated due to a substantially abrupt occurrence of a load when a clutch is connected thereon by reducing the speed of a power steering motor before the clutch is connected thereon. The method and apparatus include sensing, by a sensor, a pressure of an air tank and an on position of an air pressure; reducing, by an inverter, a speed of a power steering motor by controlling the voltage applied to the power steering motor when the pressure of the air tank is less than a setup value or when the air pressure switch is on; and in response to reducing the speed of the power steering motor, maintaining a clutch in an engaged position to transmit power from the power steering motor to an air compressor.</p> |
