Abstract
A four-stage digital voltage distribution system is provided with a multi-bridge relay assembly to deliver pulsed direct current to a dielectric actuator. A first stage of operation opens a forward voltage flow from a high voltage source through a passive signal conditioner before activating the actuator and passing through a forward diode to ground. A second stage cuts off the forward voltage flow to the dielectric actuator; thereby, shorting the dielectric actuator and causing a reverse discharge flow through a reverse diode. A third stage opens a reverse voltage flow through the signal conditioner before activating the dielectric actuator and passing through the reverse diode to ground. A fourth stage cuts off the reverse voltage flow to the charged dielectric actuator; thereby, shorting the dielectric actuator and causing a forward discharge flow through the forward diode. The four stages continuously loop to deliver pulsed DC to the actuator.
