Abstract

The invention relates to a power module device and a transport refrigeration system. The power module device is used for equipment taking a battery or / and fuel as power, has a working mode and comprises: a DC voltage reduction module or / and a DC voltage boosting module, wherein the DC voltage reduction module is arranged to convert at least a DC voltage reduction provided by the battery into a low-voltage output DC for output, and the DC voltage boosting module is arranged to convert a low-voltage input DC provided by a fuel-powered device into a high-voltage DC for output; and a control module connected with a transportation refrigeration unit and used for controlling the operation of the DC voltage reduction module or / and the DC voltage boosting module in the working mode. According to the invention, the arrangement space can be effectively saved, the original complex wiring harness connection layout can be simplified, the cost can be reduced, great convenience can be brought to theoperation and maintenance work of equipment such as a transportation refrigeration unit and the like, and the system can be compatibly applied to various types of equipment taking a battery and / or a fuel cell as power.

Description

technical field [0001] The present invention relates to the technical field of power equipment, and in particular to a power module device for equipment powered by batteries or / and fuels (such as a transport refrigeration unit on a vehicle), and a transport refrigeration system including the power module device. Background technique [0002] The transport refrigerated unit can be installed on a vehicle such as an electric truck for refrigerated goods during transportation, etc. Such a transport refrigerated unit is generally equipped with such as compressors, electric heaters, fans, valves, logic control Boards and other equipment or devices. Typically, an inverter is used to drive the compressor in the transport refrigeration unit, a low voltage DC power supply is used to power the fan motors, valves, etc. in the transport refrigeration unit, and another power unit is used to control the drive Electric heaters etc. in transport refrigerated units. This will result in a ve...
