Abstract
A transformer-coupled gate-drive power regulator system is provided that includes a feedback stage that generates a PWM signal having a duty-cycle that is based on a magnitude of an output voltage in an output stage. A switch driver stage configured to provide each of a first control signal and a second control signal based on the PWM signal. A switching stage comprising a first transformer input stage, a second transformer input stage, and a control switch. The first transformer input stage activates the control switch via the first control signal while the second transformer input stage is deactivated, and the second transformer input stage activates the control switch via the second control signal while the first transformer input stage is deactivated. The control switch can be configured to provide current through an output inductor in the output stage to generate the output voltage in response to being activated.
