The high voltage is obtained either by a step-up transformer from the mains, or a motor-generator set, or alternatively from batteries and a vibrator with a high-tension coil. The battery-operated instruments, are most popular as they are easily portable and most suited for field use. Such an instrument is illustrated in Fig. 10.53. 

Step-up transformer (F) maintains a high voltage of 2000 to 5000 V, which helps the arc to jump the gap,... 

Do note that when using step-up transformers (induction coils) that in order to create the high voltage electromagnetic field in them, you must use either AC or pulsed DC current. The capacitor in an induction ignition system does this pulsing. In the above circuit the capacitor is in the inverter (50-60Hz). 

To ignite and operate the lamp, a step-up transformer is required. 

The most common type of power supplies for mercury lamps with large arc lengths combine a step-up transformer and a "ballast" capacitor placed in the secondary circuit of the transformer (see Figure 3.10). Since the lamp power depends on its capacitance, the step-wise power can be simply varied by switching capacitors as long as the lamp is operated at appropriate cooling conditions. 

In the single-shaft arrangement, there is only one electric generator, driven by both the gas turbine and the steam turbine. This means that the electric power plant is simpler, because there is only one step-up transformer and one bay to connect to the grid. 

Transformers have a magnetic material (typically, Fe) and two inductors wrapped around it the magnet increases by a few thousandfold the mutual inductance Mbetween the two loops. Transformers are used to increase (step-up transformer) or decrease (step-down transformer) the voltage in the second circuit relative to the first. 

Until the recent development of switched mode power supplies (SMPS), most industrial precipitators were energized from some type of 50-60 Hz rectified high voltage equipment. This basically comprised a suitably designed and insulated step-up transformer, the output from which can be controlled by employing silicon controlled rectifiers to modulate the incoming... 

Among the types of equipment built were the inductor-alternator with step-up transformer and parallel-resonant tuned circuit, the SCR inverter with step-up transformer, and the mobile vacuum tube high power-amplifier. In the discussion of this equipment which follows, it is intended only to consider some of the major components of a corona power supply and to outline to the chemist and the chemical engineer a general approach to audiofrequency power generation. Without the full details of a particular application, it is impossible to select the most... 

The inverter output is fed to a step-up transformer delivering up to 12,000 volts r.m.s. This transformer is a dry type, potted with silicone rubber, with integral high voltage terminals. The particular transformer used was built as a compromise between low cost, size, and electrical capability. Rated at 3 KVA, the transformer was only 6 inches X 6 inches X 7 inches high overall. 

Figure 2 shows the basic inverter circuit. In operation as a corona generator, capacitor C is replaced by the step-up transformer and corona reactor. 

The most common type of power supplies for mercury lamps with large arc lengths combine a step-up transformer and a ballast capacitor placed in the secondary circuit of the transformer. 

Attach the electrode-connecting wire to one side of the output of a 1 10 step-up transformer. Drive the input to this transformer from a physiological stimulator that can give pulses of up to 100 V output. (This enables the final voltage on the electrode to be up to 1000 V).
