The invention discloses an integrated device for starting a diesel engine and charging a battery, as well as a diesel locomotive, belongs to the technical field of locomotives, and solves the technical problems that internal components of the conventional diesel locomotive are large in sizes and high in cost. The integrated device comprises a chopper circuit, a converter and a controller; when the diesel engine is started, the controller is adopted to drive the chopper circuit, the output voltage of the battery is boosted to a first intermediate voltage, the controller is further used to drive the converter, and the first intermediate voltage is inverted into the alternating current and is output to a generator, so that the generator is operated in the motor state to start the diesel engine; when the battery is being charged, the diesel engine is used for driving the generator to generate power, the controller is used for driving the converter to rectify the alternating current generated by the generator into a second intermediate voltage, and the controller is further used for driving the chopper circuit to reduce the second intermediate voltage for charging the battery. The integrated device can be applied to the diesel locomotive.
Description
technical field [0001] The invention relates to the technical field of locomotives, in particular to a diesel locomotive with an integrated device for starting a diesel engine and charging a storage battery. Background technique [0002] The traditional DC drive diesel locomotive uses a DC starter generator to start the diesel engine and charge the battery. Due to the low efficiency of the DC generator, low precision of charging voltage control, and large system volume, it has been gradually eliminated. With the continuous development of science and technology, diesel locomotives with AC auxiliary system and AC main drive system have been used more and more because of their good fuel-saving performance and traction performance. [0003] Various battery charging control methods and diesel engine start-up control methods are constantly being researched and applied in vehicles. At present, diesel locomotives generally use a separate design scheme for starting the diesel engine...
