PROBLEM TO BE SOLVED: To provide a power conditioner capable of performing optimum output suppression control when a circulation fan either operates or stops.SOLUTION: A power conditioner comprises: a power conversion part 2; a control part 3 which controls an operation of the power conversion part 2; a casing 4 which has a circuit accommodation space for accommodating the power conversion part 2 and the control part 3; a circulation fan 27 which circulates air in the circuit accommodation space; and temperature sensors 25, 31 which detect an ambient temperature in the circuit accommodation space and/or a temperature of a power module 23 constituting a part of the power conversion part 2, and the control part 3 is configured to performs predetermined output suppression control when the temperature detected by the temperature sensors 25, 31 exceeds a predetermined threshold so as to change the threshold based upon an operation state of the circulation fan 27.SELECTED DRAWING: Figure 1 |
