摘要： In a power phase period when in normal operation, switch portions SW2H and SW2L and switch portions SW3H and SW3L are turned ON, respectively, and switch portions SW1H and SW1L are turned OFF. And floating power supply is provided from an electrostatic capacitance element CS to buses A and B, a floating control circuit 4, a transmitter circuit 5, and a receiver circuit 6, respectively. In a data phase period, the switch portions SW1H and SW1L are turned ON, and the switch portions SW2H, SW2L, SW3H, and SW3L are turned OFF. By that manner, the electrostatic capacitance element CS is charged by the power supply of a battery B, and an electrostatic capacitance element CH provides the floating power supply to the floating control circuit 4, the transmitter circuit 5, and the receiver circuit 6, respectively. By this manner, a floating switch unit 7 in which the number of the switch portions is considerably reduced can be configured.

摘要： Apparatus for preventing two switches from being simultaneously closed. A pair of rollers are each movable in, and between the ends of, respective curved tracks. The rollers are each linked to a respective switch so that when its switch is closed, each roller is at the bottom of its track, and when its switch is open, each roller is at the top of its track. Each switch cannot operate if its roller cannot move. A yoke maintains the rollers a fixed distance apart so that each roller may be at the top of its track, one roller may be at the top of its track while the other roller is at the bottom of its track, and vice versa, but one roller cannot move away from the top of its track if the other roller is not at the top of its track and vice versa. If one switch attempts to close while the other switch is closed, the roller of the closed switch is pulled into a detent at the bottom of its track; the roller remains in the detent as long as the other switch attempts closure. The closed switch may reopen while its roller remains in the detent, preventing closure of the one switch until its attempt at closure ceases. If the switches attempt simultaneous closure, one roller is preferentially held at the top of its track, while the other roller moves to the bottom of its track.

摘要： We describe a system for controlling very large numbers of power semiconductor switching devices (132) to switch in synchronization. The devices are high power devices, for example carrying hundreds of amps and/or voltages of the order of kilovolts. In outline the system comprises a coordinating control system (110, 120), which communicates with a plurality of switching device controllers (130) to control the devices into a plurality of states including a fully-off state, a saturated-on state, and at least one intermediate state between the fully-off and saturated-on states, synchronizing the devices in the at least one intermediate state during switching.
