A Must-Have Converter to Start up the Diesel Generator

In this new report, we want to introduce how our newest DC/DC converter CBS-10K performs with a “Start-up diesel engine” software in the hybrid trains.

The CBS-10K has been created underneath rolling stock requirements and is the perfect complement to get started the diesel engine in diesel-electric hybrid trains.

How Does a Hybrid Practice Work?

Aiming for an atmosphere-helpful transportation program railway infrastructures have been upgraded in latest years for trains to contaminate less. The electric powered traction presents the environmental advantage of significantly decreasing CO2 emissions, as well as cutting down noise in massive cities.

Major providers in the railway sector have been committed to incorporating greener trains. As a end result, there has been noteworthy advancement in hybrid know-how, the place trains merge diesel and electric powered motors.

Hybrid trains are connected in series, so the electrical motor is accountable for powering the train’s wheels. The diesel combustion motor is accountable for powering the batteries and the electric powered motor, as a electrical power generator.

Trains with hybrid engines can be installed on equally electrified and non-electrified tracks (or a combination of the two), as they can use one particular of the two engines, relying on what is available. For illustration, if the batteries run out although working on a non-electrified keep track of, the prepare can normally switch to relying solely on the diesel motor.

Exactly where catenaries are electrified, vitality regeneration throughout braking may possibly not be authorized, which usually means not only owning to operate in diesel method but also hybrid mode. The use of batteries also will allow the catenary voltage to be decreased, as throughout peak strength need (accelerations) the battery will consider care of the procedure.

What Is the Application of the CBS-10K Converter in Hybrid Trains?

The CBS-10K DC/DC converter enables educate shunting at low speed when energy is not readily available from the catenary, by supplying the rectifier to do the job as an inverter when setting up the engine. This “Diesel Engine Starting up System”  is mostly observed in hybrid trains, currently being in a position to power the train’s engines from the catenary or, making use of a diesel generator, to power the traction inverter.

How Does the Converter Perform in the Hybrid Train?

The device can be put in inside the train to remodel the battery voltage (110Vdc) to a larger voltage direct present-day (DC) bus (500Vdc). The coach in catenary operation provides power to all systems by means of the DC/DC converter (1500/500Vdc).

If there is a catenary failure, the CBS-10K DC/DC converter will use the battery voltage to feed the bidirectional rectifier as a result of the 500Vdc bus, which will act as an inverter, feeding the alternator (motor in this scenario) so that the diesel generator starts off.

Once the generator is begun, it switches to “diesel mode”, where by the generator feeds the engines via the alternator and the traction inverter, passing by way of the rectifier.

In addition to this software, the CBS-10K DC/DC converter is also capable of transferring the prepare in the depot from the train’s batteries at ultra-slow velocity to carry out servicing operations.

In these two programs, our system requires on a substantial diploma of importance as it is an crucial procedure to begin the diesel generator and work at greatest performance.

With an typical energy output of 6kW, this collection of DC/DC converters allows a parallel relationship, hence escalating the power output. All versions offer you a 500Vdc output and have been designed with SiC engineering, which gives them a large-power density.

The most amazing characteristic is its single output, providing a maximum peak electrical power of up to 10kW for 40 seconds.
