Thermal Shift
Halve the Hardware.
Halve the Hardware.
Halve the Heat.
Eliminating the avoidable thermal toll of data-centre power delivery through Differential Flux Steering (DFS).
The problem
Modern data centres do not simply take electricity from the grid and send it to the processors.
- The processor produces heat while computing. We accept that.
- But we ignore the massive, avoidable heat generated just getting power to the rack.
- The power is repeatedly converted, switched, transformed, rectified, filtered, and regulated before a single calculation occurs.
Conventional architecture
An 8-to-10 stage conversion pipeline
Every stage adds components. Every component bleeds heat.
AC is converted to DC
DC is stored in batteries
DC is converted back to AC
AC is distributed through the building
AC is converted back to DC inside the rack
Voltage is switched and transformed again
Output is rectified and regulated again
Hardware toll → thermal toll
Every conversion stage requires more components—and every component bleeds heat.
The hardware toll
- Semiconductor switches
- Magnetic cores
- Rectifiers
- Inductors
- Capacitors
- Control electronics
- Protection hardware
The thermal toll
- Switching losses
- Copper losses
- Eddy currents
- Hysteresis losses
- Rectifier losses
- Capacitor heating
- Cooling demand
The industry question
The industry is optimizing the wrong variable.
The conventional industry asks: how can we make every conversion stage slightly better?
The DFS question
DFS asks a more important question:
Why are we still using so many stages?
The Magnetic Transistor
DFS turns the magnetic core into an active power-control device.
Instead of using separate components for every function, DFS combines multiple functions inside one controlled magnetic structure.
How DFS works
Anatomy of active magnetic control
Power input
The process begins at the input coil, where raw power enters the controlled magnetic structure.
Active magnetic control
Steering coils regulate exactly where magnetic power flows through the core. Positive and negative halves of the magnetic waveform are routed into output windings of the same electrical polarity—creating inherent magnetic rectification without semiconductor switching losses at that stage.
Output and transformation
Regulated magnetic flux arrives at the output coils. Changing output winding turns provides the required voltage-transformer function, integrated into the same physical structure.
Advanced recovery
Additional controlled magnetic ports support recovery, regulation, storage, protection or auxiliary outputs—and can harvest diverted energy that would otherwise be wasted.
Architecture shift
From eight or ten stages to four or five.
DFS is not an attempt to gain a fraction of a percentage point in conventional efficiency. It is a hardware-reduction architecture. Fewer stages mean fewer components producing conversion heat.

Eradicating avoidable heat
50–60%
projected reduction in power-conversion heat
By halving the number of conversion stages—and drastically reducing repeated switching, eddy-current and hysteresis losses—we target a massive reduction in the cooling demand required before power ever reaches the processor.
Evidence position: This is a projected system-level development target for selected DFS-assisted architectures, subject to independent engineering validation—not a certified product result.
The DFS opportunity
- Halve the hardware.
- Reduce the losses.
- Reduce the heat.
- Reduce the cooling.
Benefits FAQs
What does Halve the Hardware. Halve the Heat. mean?
It summarises the DFS opportunity: consolidate multi-stage power conversion into fewer stages so there is less hardware generating conversion heat before power reaches the processor.
Is the 50–60% heat reduction a guaranteed result?
No. It is a projected development target for selected DFS-assisted architectures, subject to independent engineering validation. Actual results depend on topology, duty cycle, materials and partner measurement.
How does DFS reduce conversion stages?
DFS turns the magnetic core into an active power-control device, combining functions such as transformation, isolation, magnetic switching, rectification and regulation inside one controlled magnetic structure.
