Floating Outpouts by Technix

With this option, none of the poles ( + and - ) is connected to the ground. The machine is delivered with :

  • 2 shielded connectors ( PLUS pole and MINUS pole ),
  • two HV shielded cables

Description

this is represented with the equivalent schematics:.

Vout : Output Voltage between positive and negative terminals
V+ : Voltage between positive terminal and Chassis (which is Ground)
V- : Voltage between negative terminal and Chassis (which is Ground)
Vout = (V+)(V-)


Insulation


With standard floating option, TECHNIX provides insulation for a maximum external voltage of 10% of the full voltage range of the generator.
This means we provide an insulation of 110 % of Vout max on one or the other terminals referenced to ground/chassis.

Vinsulation = | Vout | + | Vext |
Where:
Vout is the output voltage of the generator
Vext is the maximum external potential introduced on one or the other pole of the generator (refered to the chassis)



For instance a generator delivering 0 to 5 KV with a standard floating option will accept a maximum external voltage of |500 V| referenced to chassis/ground.
The other terminal voltage could be then at |5.5 KV| referenced to chassis/ground.

Please contact us, for applications where external voltage is more than 10% of Vout.


Control is ground referenced


With our floating option, whole electronics of control is referenced to ground and insulation is made inside of the machine providing a maximum of safety.

This allows the user to work safety even on front panel.

In case of continuity fault of any component, there is no risk to have High Voltage or external Voltage feedback.

Example

You have two generators. Each one is 1kV, 20A, 20kW and floating. You can connect the HV outputs in parallel to get up to twice the current of one generator, or in serial to get up to twice the voltage of one generator.

360足球胜负彩票Here the schematic of a parallel mounting. You don’t need a floating option in order to realise it

equivalent generator in parallel mode

equivalent generator in serial mode


Example 1 - 12 KV Floating Generator with standard floating option


In this example external voltage represented in blue, is introduced upon the negative terminal at the maximum value of 1200 V for respecting insulation.
V+, voltage on positive terminal referenced to ground, will vary from 1.2 to 13.2 kV.
Remark :
In the case of no external voltage is introduced, the output voltages will balance automatically at half of the Output Voltage, referenced to the chassis.
360足球胜负彩票Even in this case, we recommend adding protections between each generator output and the chassis (transcient or varistors).


With Vext = 0 V: At half scale, with no external voltage, the terminal voltages are automatically balanced referenced to ground.


Example 2 - 15 KV Floating Generator with Vext = 5 KV Max

this is a special floating option since the external voltage can represent more than 10% of vout.


If an external voltage of 5 kV is introduced upon positive terminal, V- will vary between -10 kV (for Vout = 15 kV) to 5 kV (for Vout = 0 V).


360足球胜负彩票If an external voltage of - 5 kV is introduced upon positive terminal, V- will vary between -5 kV (for Vout = 0 V) to 10 kV (for Vout = 15 kV).
