EA Elektro-Automatik Integrates Infineon’s 1200 V CoolSiC™ MOSFETs

EA Elektro-Automatik has integrated discrete 1200 V CoolSiC™ MOSFETs from Infineon Technologies for its bidirectional laboratory power supplies PSB 10000; the system operates with efficiencies of up to over 96 percent. Used as an electronic load, the energy is fed back into the power grid, and only a small amount of energy is dissipated in the form of heat. The power density is industry-leading with 30 kW in a single 4U 19″ housing.

INFINEONThe device series PSB 10000 features an output stage with an extended scope of operation. Typical programmable DC sources offer full output power only at maximum voltage and current. The devices from EA Elektro-Automatik, on the other hand, offer full power from as little as one-third of the output voltage or output current. Charging or discharging a vehicle battery can serve as a good example. Even if the battery voltage rises or falls, the current automatically adjusts and thus provides full power. The flexibility of the devices can save a lot of equipment when testing different electronic components.


The bidirectional laboratory power supplies PSB 10000 4U can be configured from 30 kW to 1920 kW to form a complete system. Voltages from 60 V to 2000 V and currents up to several thousand amperes are available. To facilitate the integration into a test stand, the units are equipped with analog and digital interfaces. All power supplies are equipped with Ethernet and USB; CAN, CANopen, Profibus, ProfiNet, Ethercat, ModBus, and RS232 are optionally available.
