Technical Papers SOWTER Audio TRANSFORMERS Rectifier Formula The voltage and current ratings for the HT winding can be calculated from the dc voltage and current using the formula below appropriate to your rectifier and smoothing circuit. The power rating for determining the size of the transformer is shown below as Pac (Watts). The formulae below allowances […]
Technical Papers SOWTER Audio TRANSFORMERS Rectifier Formula The table below shows the ratio and voltage equivalent to a given level in dBu from +40 dBu to -40 dBu. dBu is a logarithmic voltage notation relative to 0.7746 Volts but not related to any impedance. dBm (the traditional unit 50 years ago) is relative to 1 […]
