The BSC614-24 V is a bidirectional DC / DC converter with galvanic isolation between the high-voltage and low-voltage circuit. It is particularly suitable for use in electric, hybrid and fuel cell vehicles. In buck mode, the 24 V on-board network is supplied with a current of up to 125 A from the high-voltage side. Thanks to the bidirectionality and its diverse configuration options, the BSC614-24 V can be used in a wide variety of areas. The bidirectional operation enables additional functions, so in fuel cell applications in step-up operation the HV side of the fuel cell circuit can be started up from the 24 V on-board network. With the BSC614-24 V in step-up operation, it is even possible to emergency charge the traction battery using a jump starter cable.
The BSC614-24 V is located in the A sample status.
- Bidirectional functionality
- Complete galvanic separation between HV and LV side
- Resonant topology enables very low switching losses and excellent EMC properties
- Very high efficiency (96%)
- Extremely compact and lightweight construction
- The supplied PARAM software enables a wide range of configuration and diagnostic functions
- Standard communication via CAN interface
- Optional operation without CAN possible (CAN-less mode)
On the one hand, the device is based on a series-resonant transformer stage, through which the galvanic separation is implemented. On the other hand, the desired voltage can be set in the respective operating mode by means of two step-up / step-down converters that work in a toothed manner to reduce ripple. Due to the resonant topology of the transformer stage and the so-called auto-commutation of the step-up / step-down converter, not only losses are limited to a minimum, but excellent EMC properties are also achieved. During the development of the device, priority was given to a compact, vibration-proof and lightweight design in order to enable use in almost all applications and installation locations.
