    Abstract: A capacitor connected to the battery in parallel; a step-up converter connected to the battery and the first capacitor; another capacitor connected to the step-up converter in parallel; an inverter connected to the step-up converter and the other capacitor in parallel; a potential line connecting a negative-side terminal of the battery to the capacitor, the step-up converter, the other capacitor, and the inverter in the stated order; and a bypass path formed, when a lower arm switching device of the step-up converter has a short-circuit failure, from cutting the reference electric potential line at a position including at least any one of a position between the negative-side terminal and the capacitor and another position between the step-up converter and the other capacitor. The bypass path bypasses the lower arm switching device and connects the negative-side terminal to the inverter.

    Abstract: A system includes a control module and a monitor module. The control module selectively operates a component of the system in an ON state. The system receives power from an electrical grid. The monitor module selectively detects a fault event of the electrical grid in response to (i) an amount of current drawn by the component or (ii) a voltage of power received by the component. In response to detecting the fault event, the control module switches the component from the ON state to a second state, determines a first delay period according to a random process, identifies an apparent conclusion of the fault event, and in response to the apparent conclusion of the fault, waits for the first delay period before switching the component back to the ON state. The component consumes less power in the second state than in the ON state.

    Abstract: A power switching device, a power switching method, and a projection device using the power switching device are provided. In the power switching method, a first power and a second power are received, and the voltage level of the first power is compared with the voltage level of the second power. One of the first power and the second power having the higher voltage level is sustained by using one of the first power and the second power having the lower voltage level until one of the first power and the second power having the higher voltage level stabilizes. At least one of the first power and the second power having the higher voltage level and being already stabilized is output as an output voltage.

    Abstract: A system and method for supplying power to a variable speed motor for rotating a shaft may include generating an A/C output having a variable frequency corresponding to speed of a prime mover, where the speed of the prime mover is equal to or greater than a predetermined speed limit. The A/C output of the prime mover may be distributed to the variable speed motor such that the speed of the variable speed motor is varied relative to the frequency of the A/C output. The variable speed motor may be electrically disconnected from the A/C power when the speed of the prime mover being used to drive the variable speed motor is equal to or within a predetermined range of the predetermined speed limit. An alternate A/C output may be distributed to the variable speed motor after the A/C power is electrically disconnected from the variable speed motor.
