WebThe RC time constant of the snubber should, therefore, be much smaller than the switching period (consider the effect of ... Avoid using wirewound resistors. The layout should not introduce stray inductance, especially in high current paths. The transformer used in flyback converters should be designed to reduce leakage inductance and minimize ... WebIn the example below, if the T.C is actually rated 480 – 120 volts, the transformer ratio is 4:1 (480 / 120 = 4). Applying a test voltage of 120 volts to the primary will result in a secondary voltage of 30 volts (120 / 4 = 30). If transformer is subtractive polarity, the voltmeter will read 90 volts (120 – 30 = 90).
