Power storage apparatus

Abstract: A power storage apparatus provided with a capacitor module and a power storage control circuit is connected between a generator and an electrical load. The capacitor module includes a plurality of capacitors and a plurality of switching devices which are connected in series with the capacitors, respectively, the capacitors and the switching devices together constituting a plurality of series circuits which are connected parallel to each other. When starting up the generator, the power storage control circuit controls only the specified switching device to become ON in order to quickly charge the capacitor which is connected in series with the switching device so that a voltage of the capacitor module is increased and a power source for starting up the generator is produced as high speed.

Low power scheme to protect the low voltage capacitors in high voltage io circuits

Abstract: An input/output (IO) circuit includes a first bias circuit and a second bias circuit coupled to a node. A first capacitor and a second capacitor are being cascaded and coupled to the node. The node is defined between the first capacitor and the second capacitor. A pad is coupled to the node. The first bias circuit maintains a voltage at the node below a threshold during a transmit mode and a receive mode of the IO circuit and the second bias circuit maintains the voltage at the node below the threshold during the receive mode. The voltage at the node is dependent on a voltage at the pad during the receive mode.
