| 发明名称 | Over-current damage prevention method and apparatus for subsidiary inverter of electric bus | ||
| 摘要 | 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. | ||

| 主权项 | 1. An over-current damage prevention method for a subsidiary inverter of an electric bus, comprising: sensing, by a sensor, a pressure of an air tank and an on position of an air pressure switch; reducing, by a controller provided in 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, by the inverter, a clutch in an engaged position to transmit power for the power steering motor to an air compressor. | ||
