The invention discloses an integrated passenger train inverting module and an inverter box. The inverting module comprises a cabinet body, a main circuit unit, a sensor detecting unit and a control unit; the main circuit unit, the sensor detecting unit and the control unit are integrally arranged in the cabinet body; and the control unit has multiple voltage output control modes; the sensor detecting unit detects signals of the main circuit unit; and the control unit controls the main circuit unit to convert a direct current into a three-phase alternating current based on the needed voltage output control mode and signals detected by the sensor detecting unit. The inverter box comprises a box body and more than one inverting module arranged in the box body. The integrated passenger train inverting module and the inverter box have the advantages such as compact structure, high degree of integration, easy installation, maintenance and debugging, and good compatibility.
