The year-old became only the third ever Welsh darts world champion when he beat Dutchman Raymond van Barneveld in However, having claimed the top prize in the sport, Burnett's world came crashing down in October after it emerged he had tested positive for cocaine at a competition one year earlier.
He was slapped with an month ban from the game and has faced a lengthy battle with depression. And the Cwmparc product has revealed he regularly contemplated taking his own life while he was banned from darts.
It's said it [testing] was random. No way," he told the Inside the BDO podcast. It was my own stupid fault. This argument for closed-loop power control also applies to all of the methods that follow below.
The power processed by the inverter can be decreased by reducing the on-time of the switches in the inverter. Power is only sourced to the work coil in the time that the devices are switched on.
The load current is then left to freewheel through the devices body diodes during the deadtime when both devices are turned off. However, a significant drawback of this method is the commutation of heavy currents between active devices and their free-wheel diodes.
Forced reverse recovery of the free-wheel diodes that can occur when the duty ratio is considerably reduced. For this reason duty ratio control is not usually used in high power induction heating inverters.
The power supplied by the inverter to the work coil can be reduced by detuning the inverter from the natural resonant frequency of the tank circuit incorporating the work coil.
As the operating frequency of the inverter is moved away from the resonant frquency of the tank circuit, there is less resonant rise in the tank circuit, and the current in the work coil diminishes.
Therefore less circulating current is induced into the workpiece and the heating effect is reduced. In order to reduce the power throughput the inverter is normally detuned on the high side of the tank circuits natural resonant frequency.
This causes the inductive reactance at the input of the matching circuit to become increasingly dominant as the frequency increases.
Therefore the current drawn from the inverter by the matching network starts to lag in phase and diminish in amplitude. Both of these factors contribute to a reduction in the real power throughput.
In addition to this the lagging power factor ensures that the devices in the inverter still turn on with zero voltage across them, and there are no free-wheel diode recovery problems.
This can be contrasted with the situation that would occur if the inverter were detuned on the low side of the work coil's resonant frequency.
ZVS is lost, and the free-wheel diodes see forced reverse-recovery whilst carrying significant load current. This method of controlling power level by detuning is very simple since most induction heaters already have control over the operating frequency of the inverter in order to cater for different workpieces and work coils.
The downside is that it only provides a limited range of control, as there is a limit to how fast power semiconductors can be made to switch.
This is particularly true in high power applications where the devices may already be running close to maximum switching speeds. High power systems using this power control method require a detailed thermal analysis of the results of switching losses at different power levels to ensure device temperatures always stay within tolerable limits.
For more detailed information about power control by detuning see the new section below labelled "LCLR network frequency response. The power supplied by the inverter to the work coil can be varied by altering the value of the matching network components.
The L-match network between the inverter and the tank circuit technically consists of an inductive and a capacitive part.
But the capacitive part is in parallel with the work coil's own tank capacitor, and in practice these are usually one and the same part.
Therefore the only part of the matching network that is available to adjust is the inductor. The matching network is responsible for transforming the load impedance of the workcoil to a suitable load impedance to be driven by the inverter.
Altering the inductance of the matching inductor adjusts the value to which the load impedance is translated. In general, decreasing the inductance of the matching inductor causes the work coil impedance to be transformed down to a lower impedance.
This lower load impedance being presented to the inverter causes more power to be sourced from the inverter.
Conversely, increasing the inductance of the matching inductor causes a higher load impedance to be presented to the inverter.
This lighter load results in a lower power flow from the inverter to the work coil. The degree of power control achieveable by altering the matching inductor is moderate.
There is a also a shift in the resonant frequency of the overall system - This is the price to pay for combining the L-match capacitance and tank capacitance into one unit.
The L-match network essentially borrows some of the capacitance from the tank capacitor to perform the matching operation, thus leaving the tank circuit to resonate at a higher frequency.
For this reason the matching inductor is usually fixed or adjusted in coarse steps to suit the intended workpiece to be heated, rather than provide the user with a fully adjustable power setting.
The power supplied by the inverter to the work coil can be varied in coarse steps by using a tapped RF power transformer to perform impedance conversion.
Although most of the benefit of the LCLR arrangement is in the elimination of a bulky and expensive ferrite power transformer, it can cater for large changes in system parameters in a way that is not frequency dependent.
The ferrite power transformer can also provide electrical isolation as well as performing impedance transformation duty to set the power throughput.
Additionally if the ferrite power transformer is placed between the inverter's output and the input to the L-match circuit its design constraints are relaxed in many ways.
Firstly, locating the transformer in this position means that the impedances at both windings are relatively high. It is easier to design a conventional ferrite power transformer for these conditions.
The massive circulating current in the work coil is kept out of the ferrite transformer greatly reducing cooling problems. Secondly, although the transformer sees the square-wave output voltage from the inverter, it's windings carry currents that are sinusoidal.
The lack of high frequency harmonics reduces heating in the transformer due to skin effect and proximity effect within the conductors.
Finally the transformer design should be optimised for minimum inter-winding capacitance and good insulation at the expense of increased leakage inductance.
The reason for this is that any leakage inductance exhibited by a transformer located in this position merely adds to the matching inductance at the input to the L-match circuit.
Therefore leakage inductance in the transformer is not as damaging to performance as inter-winding capacitance. When the work coil is driven by a voltage-fed full-bridge H-bridge inverter there is yet another method of achieving power control.
