Isn't it a simple case of using a DC-blocking capacitor in series with the primary?? Seems both affordable and practical...
no, it is a matter of ratios. at 50% duty cycle the core is completely reset and operates at zero FLUX bias, anything else puts bias on the core. that is why you find reset windings on forward converters.
the area above zero and below need to cancel out.
