The demonstration
display of a dielectric liquid cooling system using the new BEHLKE
PU-2 pump unit. Various malfunctions can be simulated to
demonstrate the safety features of the intelligent PU-2 pump.
Top left in the cooling box is a callable cell phone (i-phone 5)
immersed in the liquid, to show the dielectrical properties of the FPFE coolant. In the lower cooling box are two resistors of 47 Ohm each, which are connected in series to the mains voltage (240 VAC). The resulting power dissipation is 560 Watt, which can be removed either by the active radiator (AR-800W) or the heat exchanger (HE-10). At the right side of the resistor box is a high-voltage high-frequency switching unit (FSWP 51-01) with a transparent viewing window. The unit can generate square wave pulses from 0 to 5 kV at a repetition rate of up to 3 MHz. The rise and fall time is less than 6 ns. Thanks to the DLC cooling, the max. power dissipation in this small plastic housing can be up to 1500 Watt. |

| The high voltage demonstration set-up in operation with 20 kV input voltage. All switch control inputs are unshielded and connected in parallel. All switches are in a high side configuration with a 5 Kiloohm load at the output (except the push-pull switch). On the scope display: Yellow = common TTL control signal, blue = 6 kV push-pull switch, violet = 12 kV variable on-time switch, green = 24 kV fixed on-time switch. All three switches are operated at the same time at about 90% of their maximum operating voltage. The high voltage pulse rise times of the three switches are between 5 to 8 ns. Nice to see that the three switches do not interference each other, even with unshielded input wiring. The newly developed VC4 control circuit guarantees a perfect EMC even under the absolute worst conditions! |

Liquid cooled high-power high-voltage switches in a tubular
housing. The switches are equipped with a special noise filter
(black tube) and have a separate control unit. Top: MOSFET switch, 100 kV / 200 A / 20 kW. Middle: MOSFET switch, 150 kV / 200 A / 30 kW. Below: MOSFET switch, 150 kV / 400 A / 40 kW In the background at the blue column: A 150 kV, 200 A MOSFET push-pull switch in a plastic standard housing, also with DLC direct liquid cooling. |
 |
| An issue for highly qualified engineers: The radio controlled BEHLKE shark. |
 |
| At last, they got it. |
 |
| Wow! |
 |
|
Thank you for your visit and see you soon in Nürnberg and San Francisco!
