Abstract
An apparatus, system, and method are disclosed for a single stage hybrid charge pump. A switch module is connected to ground. An inductance module is connected between a DC voltage source and the switch module. A first capacitance module is connected to the switch and to the inductance module. A first current blocking module is connected between the DC voltage source the first capacitance module. A second capacitance module is connected to ground. A second current blocking module is connected to a node between the first capacitance module and the first current blocking module and is also connected to the second current blocking module. The switch module is operated to switch between an open state and a closed state thereby causing a voltage across the second current blocking module to increase until it is limited by a voltage limiting module.
