The year-old became only the third ever Welsh darts world Author: Ian Mitchelmore.
The midfielder was temporarily suspended but escaped a ban from the Football Association after failing a drugs test in May almost a year after his newborn son Jake Junior died.
And Burnett feels he was unfairly punished after going through a similar tragedy before he was banished into the darting wilderness after his positive test.

This has a number of advantages. Firstly, it makes either the current or the voltage waveform become sinusoidal. This minimises losses in the inverter by allowing it to benefit from either zero-voltage-switching or zero-current-switching depending on the exact arrangement chosen.
The sinusoidal waveform at the work coil also represents a more pure signal and causes less Radio Frequency Interference to nearby equipment.
This later point becoming very important in high-powered systems. We will see that there are a number of resonant schemes that the designer of an induction heater can choose for the work coil:.
The work coil is made to resonate at the intended operating frequency by means of a capacitor placed in series with it. This causes the current through the work coil to be sinusoidal.
The series resonance also magnifies the voltage across the work coil, far higher than the output voltage of the inverter alone. The inverter sees a sinusoidal load current but it must carry the full current that flows in the work coil.
For this reason the work coil often consists of many turns of wire with only a few amps or tens of amps flowing.
Significant heating power is achieved by allowing resonant voltage rise across the work coil in the series-resonant arrangement whilst keeping the current through the coil and the inverter to a sensible level.
This arrangement is commonly used in things like rice cookers where the power level is low, and the inverter is located next to the object to be heated.
The main drawbacks of the series resonant arrangement are that the inverter must carry the same current that flows in the work coil.
In addition to this the voltage rise due to series resonance can become very pronounced if there is not a significantly sized workpiece present in the work coil to damp the circuit.
This is not a problem in applications like rice cookers where the workpiece is always the same cooking vessel, and its properties are well known at the time of designing the system.
The tank capacitor is typically rated for a high voltage because of the resonant voltage rise experienced in the series tuned resonant circuit.
It must also carry the full current carried by the work coil, although this is typically not a problem in low power applications. The work coil is made to resonate at the intended operating frequency by means of a capacitor placed in parallel with it.
The parallel resonance also magnifies the current through the work coil, far higher than the output current capability of the inverter alone.
The inverter sees a sinusoidal load current. However, in this case it only has to carry the part of the load current that actually does real work.
The inverter does not have to carry the full circulating current in the work coil. This is very significant since power factors in induction heating applications are typically low.
This property of the parallel resonant circuit can make a tenfold reduction in the current that must be supported by the inverter and the wires connecting it to the work coil.
Conduction losses are typically proportional to current squared, so a tenfold reduction in load current represents a significant saving in conduction losses in the inverter and associated wiring.
This means that the work coil can be placed at a location remote from the inverter without incurring massive losses in the feed wires.
Work coils using this technique often consist of only a few turns of a thick copper conductor but with large currents of many hundreds or thousands of amps flowing.
This is necessary to get the required Ampere turns to do the induction heating. Water cooling is common for all but the smallest of systems.
This is needed to remove excess heat generated by the passage of the large high frequency current through the work coil and its associated tank capacitor.
In the parallel resonant tank circuit the work coil can be thought of as an inductive load with a "power factor correction" capacitor connected across it.
The PFC capacitor provides reactive current flow equal and opposite to the large inductive current drawn by the work coil.
The key thing to remember is that this huge current is localised to the work coil and its capacitor, and merely represents reactive power sloshing back-and-forth between the two.
Therefore the only real current flow from the inverter is the relatively small amount required to overcome losses in the "PFC" capacitor and the work coil.
There is always some loss in this tank circuit due to dielectric loss in the capacitor and skin effect causing resistive losses in the capacitor and work coil.
Therefore a small current is always drawn from the inverter even with no workpiece present. When a lossy workpiece is inserted into the work coil, this damps the parallel resonant circuit by introducing a further loss into the system.
Therefore the current drawn by the parallel resonant tank circuit increases when a workpiece is entered into the coil. Or simply "Matching".
This refers to the electronics that sits between the source of high frequency power and the work coil we are using for heating.
However this can be contrasted with the inverter that generates the high frequency power. The inverter generally works better and the design is somewhat easier if it operates at fairly high voltage but a low current.
Typically problems are encountered in power electronics when we try to switch large currents on and off in very short times. The comparatively low currents make the inverter less sensitive to layout issues and stray inductance.
We can think of the tank circuit incorporating the work coil Lw and its capacitor Cw as a parallel resonant circuit. This has a resistance R due to the lossy workpiece coupled into the work coil due to the magnetic coupling between the two conductors.
See the schematic opposite. In practice the resistance of the work coil, the resistance of the tank capacitor, and the reflected resistance of the workpiece all introduce a loss into the tank circuit and damp the resonance.
Therefore it is useful to combine all of these losses into a single "loss resistance. This resistance represents the only component that can consume real power, and therefore we can think of this loss resistance as the load that we are trying to drive power into in an efficient manner.
When driven at resonance the current drawn by the tank capacitor and the work coil are equal in magnitude and opposite in phase and therefore cancel each other out as far as the source of power is concerned.
This means that the only load seen by the power source at the resonant frequency is the loss resistance across the tank circuit.
Note that, when driven either side of the resonant frequency, there is an additional "out-of-phase" component to the current caused by incomplete cancellation of the work coil current and the tank capacitor current.
This reactive current increases the total magnitude of the current being drawn from the source but does not contribute to any useful heating in the workpiece.
The job of the matching network is simply to transform this relatively large loss resistance across the tank circuit down to a lower value that better suits the inverter attempting to drive it.
