摘要： An uninterruptible power supply having a controllable leakage current is disclosed. The leakage current is controlled by adjusting a switching speed (i.e., dV/dt rate) of switches in the output inverter (i.e. DC-AC converter stage). Leakage current can be reduced by reducing the switching speed (dV/dt rate) of the output inverter switches. In one embodiment, leakage current is held constant or moderated as output power decreases by reducing the switching speed (responsive to leakage current) as output power decreases. The switching speed can be adjusted by adjusting the gate resistance or gate voltage. Increasing the gate resistance or decreasing the gate voltage will cause a reduction in the switching speed, and increase in leakage current. Conversely, reducing the gate resistance, or decreasing the gate voltage will cause an increase in switching speed, and increase in leakage current. The present invention is applicable to any uninterruptible power supply having output inverter switches.
摘要翻译：公开了一种具有可控泄漏电流的不间断电源。通过调节输出逆变器（即DC-AC转换器级）中的开关的开关速度（即，dV / dt率）来控制漏电流。通过降低输出逆变器开关的开关速度（dV / dt率）可以降低泄漏电流。在一个实施例中，当输出功率降低时，随着输出功率降低开关速度（响应于泄漏电流）而使漏电流保持恒定或缓和。可以通过调整栅极电阻或栅极电压来调整开关速度。增加栅极电阻或降低栅极电压将导致开关速度的降低，并增加漏电流。相反，降低栅极电阻或降低栅极电压将导致开关速度的提高和漏电流的增加。本发明适用于具有输出逆变器开关的任何不间断电源。

摘要： A medium or high voltage multi-inverter system is described, in which multiple inverter cells are included in a phase line to increase the voltage level supported by the system, and support higher voltage loads such as AC three-phase motors. In one configuration, five cells are used: two each in two phase lines, and one in a third phase line. In one of the phase lines having two cells, a second cell is series connected in reverse polarity, generates a phase matching the phase of the third line, while the other cell in the phase line generates an output with a different phase. One or more failure switches may be included to allow for short-circuiting of the output poles of one or more of the cells, so that in case of cell failure, the system can continue operation. For example, switches may be employed for the second cells in the two phase lines having two cells, and those cells may be available as spare cells in case of a cell failure.

摘要： In an image forming apparatus, a setting part sets a first waiting time, which lasts from a completion of an ejecting operation of one sheet of recording paper to a start of supply of a subsequent sheet in a one-side printing or a second waiting time, or a second waiting time, which lasts from a completion of ejecting operation of one sheet of recording paper to a start of resupply of the one sheet of recording paper in both-side printing. A determining part detects a difference in time length between the first or second waiting time, a maintenance time required by a head maintenance operation and a cap timer time, which is a time during which a nozzle of the recording head is allowed to be maintained in an uncapped state, and determines a time of restarting a printing operation after execution of the maintenance operation based on the detected difference.
