Abstract:
1. A system for tailoring a rate-of-change of a capacitor voltage across a capacitor, the system comprising: a first circuit group including at least two parallel circuit branches in series with a first voltage source and a first plate of the capacitor, each parallel circuit branch including a current source and a switch connected in series, each of the current sources configured to supply a different amount of current than the other current sources; a second voltage source in electrical connection with a second plate of the capacitor; and a control circuit configured to receive a voltage reference and to monitor the capacitor voltage; wherein the control circuit is configured to control closure of the switches in the first circuit group in accordance with a specified timing scheme and in a specified order based on the monitoring of the capacitor voltage so as to achieve a first rate-of-change in the capacitor voltage; and wherein the specified order starts with closure of the switch in series with the current source providing a smallest amount of current and moves in order of increasing current to closure of the switch in series with the current source providing a largest amount of current, each closed switch remaining closed as a next switch in the order is closed.
