Abstract

Disclosed is a direct current power supply circuit with adjustable output voltage of a fuel frequency conversion generating set. The direct current power supply circuit includes a three-phase full-bridge rectifier and filter circuit, a DC-DC conversion module circuit, a PWM drive control module and a sampling module. An input end of the three-phase full-bridge rectifier and filter circuit is connected to a three-phase AC end. An output end of the three-phase full-bridge rectifier and filter circuit is connected to an input end of the DC-DC conversion module circuit. The sampling module is usedfor collecting input electrical signals, output electrical signals and temperature of the DC-DC conversion module circuit. An output port of the sampling is connected to an input end of the PWM drivecontrol module. An output end of the PWM drive control module is connected to a control end of the DC-DC conversion module circuit. An energy conversion process of eh set is simplified, an AC-DC-DC topology is used to replace an AC-DC-AC-DC-DC topology, and the load-bearing ability of the set is greatly improved.

Description

technical field [0001] The invention relates to the field of general gasoline engines and switching power supplies, in particular to a direct current power supply circuit with adjustable output voltage of a fuel oil frequency conversion generator set. Background technique [0002] With the development of new energy technology and the improvement of living standards, people have more and more demands on the application of various DC loads in the field, such as various battery packs, DC motors and motors, mobile phone base station emergency systems, etc. The demand for battery-like applications is also increasing. But no matter what kind of battery pack, its power is limited, so it is necessary to charge the battery pack in time to meet the increasingly vigorous use needs of users. [0003] At present, there is not yet a complete set of integrated modules integrating system control and inverter DC output in the industry of general fuel oil units. The user either uses the alt...
