Abstract:
A pulse width modulated power converter having a single time multiplexed symmetry correction circuit operative to vary the pulse width of output drive pulses applied to an output transformer. As a result, the average current and thus the volt second product seen by each half of the transformer primary winding will be equal under steady state conditions. The transformer drive remains balanced over the entire dynamic range to prevent unwanted saturation of the transformer core.
