A 40µF, 600V paper capacitor is available but we need one having rating of about 300µF. It is proposed to use a transformer to modify the 40µF so that it appears as 300µF. The following transformer ratios are available: 120V/330V; 60V/450V; 480V/150V. Which transformer is the most appropriate and what is the reflected value of the 40µF capacitance? To which side of the transformer should the 40µF capacitor be connected?
