The circuit for the supply is shown below, and uses separate rectifiers and capacitors for each channel. Only the transformer is shared, so channel interactions are minimised. A single ±35V supply (i.e. using only a single bridge and set of filter capacitors) will work just as well in the majority of cases. Figure 1 - ±35V Power Supply
For high voltage gain, a transformer-less step-up DC/DC converter based on a switched inductor (SL) and switched capacitor (SC) techniques have been proposed in [ 110 ]. Furthermore, it can reduce the voltage stress on the semiconductor switches, but the cost will increase because of the two switches.
To measure the main capacitance and the loss factor tan d, the HV cable must be connected to the central conductor, usually at the air side terminal. The measurement input should be connected to the measurement tap and UST-method (Ungrounded Specimen Test) must be used. The flange must be grounded.
The secondary winding charges two boosting capacitors in parallel as switches during the switch-on period, and two boosting capacitors are discharged in series during the switch-off period. Thus, the converter has high voltage gain with appropriate duty ratio.
High-efficiency DC/DC converters are in high demand in the lighting industry as power supply and driver circuits, for instance. A new generation in lighting has begun with the invention of light-emitting diodes (LED). In [ 154, 155 ], LED systems provide better lighting because they have a longer life, smaller size and improved robustness.
The grid-injected current and DC link voltage are regulated by employing an FFL controller, as presented in [ 198 ]. Concerning structural complexity, system nonlinear features are altered into linear subsystems, and afterwards, a control law is implemented in these subsystems.

It''s worth showing the effect of series resonance between the capacitor and transformer''s primary inductance. The above graph shows the behaviour after the application of DC. The period between peaks is 2.12 seconds, which makes the frequency 0.47Hz. A calculation using 2,000µF and an estimated 40H gives 0.56Hz, and the figures are close enough to see …
