PSB 10000 adopts Infineon 1200V CoolSiC MOSFET


Sales of hybrid and fully electric vehicles are rapidly increasing worldwide. Consequently, the demand for testing electronic components such as motors, controls, and batteries is also increasing. Testing is a critical component of electric drivetrain production, and conventional test setups require dedicated DC sources and electronic loads connected in parallel to handle bidirectional energy flow.

Infineon's CoolSiC MOSFETs have been selected for the PSB 10000 bidirectional power supply for electric drivetrain testing by EA Elektro-Automatik in Germany.

The PSB 10000 power supply from Germany's EA Elektro-Automatik (EA) operates with an efficiency of over 96 percent. When used as an electronic load, this system returns energy to the grid, with only a small amount dissipated as heat. It boasts an impressive power density of 30 kW in a single 4U, 19-inch housing.

The PSB 10000 series features an output stage with an extended operating range. Conventional programmable DC sources only output maximum power at maximum voltage and current. In contrast, EA's devices deliver full power at only one-third of the output voltage or output current.

Current automatically adjusts to provide maximum power even when the battery voltage rises or falls. This flexibility reduces the amount of equipment required to test various electronic components.

The PSB 10000 4U bidirectional laboratory power supply is flexibly configurable from 30 kW to 1920 kW. It can handle voltages from 60 V to 2000 V and currents reaching several thousand amperes.
