Control techniques for the single magnetic push-pull forward converter with built-in input filter

The single magnetic push-pull forward converter is a suitable topology for power delivery, supplying low voltages and fast transient currents for high performance microprocessors. This paper covers a lack of research in the literature from control techniques applied to this converter topology. Three different control techniques using adaptive voltage compensation are applied to this converter. Classical PWM voltage-mode, basic hysteretic and advanced hysteretic mode control are analyzed and simulated using a derived nonlinear averaged large signal model from the push-pull forward converter.
