Abstract: A first softstart signal indicates operation in a load phase for a boost rectifier and a second softstart signal indicates operation in a pulse drive phase which follows the load phase. A rectification transistor is actuated for the duration of the load phase in response to the first softstart circuit to generate a rising output voltage. The rectification transistor is further repeatedly actuated during the pulse drive phase in response to the second softstart circuit to generate a boosted output voltage. A first transistor coupled between a first conduction terminal and a body terminal of the rectification transistor is actuated, and a second transistor coupled between the body terminal and a second conduction terminal of the rectification transistor is deactuated, during the load phase. The first transistor is deactuated, and the second transistor is actuated, during the pulse drive phase.
