Level shifter having automatic delay adjusting function

In a level shifter, in the case where the amplitude voltage of an input signal (i.e., a first power voltage VDDL) input to an input terminal is changed to be higher and the amplitude voltage of an output signal (i.e., a second power voltage VDDH) output from an output terminal is changed to be lower, a fall delay time of the signal output from the output terminal tends to be longer than a rise delay time of the signal. However, an inverted input signal obtained by an inverter is input to a level shifting unit and also to the gate of an N-type transistor, and therefore, the N-type transistor is turned on at the fall of the input signal input to the input terminal, so as to supply a current based on the second power voltage VDDH to an output node of the level shifting unit for assisting the shift into H level performed in the level shifting unit. Accordingly, even when at least one of the amplitude voltage of the input signal and the amplitude voltage of the output signal is changed, balance between the fall delay time characteristic and the rise delay time characteristic of the output signal can be satisfactorily kept.

Method of operation controller having processor for controlling industrial machine

A method of operating a controller of an industrial machine capable of reducing a rise in temperature of a processor, easily restoring and resuming the operation even if the operation is stopped by the rise in temperature, and further possibly preventing the stop of the operation of the controller by the rise in temperature. When temperature in the controller is lower than a set value, the processor performs a plurality of processings in each predetermined period to do normal operation. When the temperature rises to a set value or higher, processing related to the controlling axes is stopped, a motor is stopped, and the processor performs only minimum or limited required processing, i.e., processing related to a man / machine interface such as processing related to a programmable controller and processing for display and operates in a low-electric-power consumption mode except the period when the processor performs the minimum or limited required processing. In addition, as the temperature rises, the operating speed of a machine controlled by the controller is reduced to reduce heat generation and the rise in temperature of the processor.

The invention discloses a safe operation method of active voltage reduction for a ground fault phase of a non-effective grounding system, and the safe operation method is applied to the ground fault safe operation of a neutral point non-effective grounding generator or power distribution network. When a single-phase ground fault occurs, an adjustable current source is applied additionally between a bus at a non-effective grounding system side and the ground, or between a circuit and the ground, or between a neutral point and the ground, or between a shunting tap at a transformer non-effective grounding system side winding and the ground, to adjust the injected current magnitude and phase and further reduce the fault phase voltage, so that the fault point voltage is lower than the ground arc continuous combustion voltage to meet the long-term non-stop safe operation requirement. According to the invention, the fault phase voltage is reduced to a non-zero safe operation value, so the permanent single-phase earth fault current is suppressed, the rising amplitude of the non-fault phase voltage is limited, the risk of non-fault phase insulation breakdown is reduced, the personal safety and equipment security risks are reduced, the occurrence of power outages is effectively prevented, and power supply reliability and security are greatly improved.

The first coil and at least part of the second coil are connected in series to receive distorted alternating current and at least that part of the second coil is connected to an output terminal. Between the coils and extending at least part of the way from the first leg to an adjacent leg is a magnetic shunt assembly to divert part of the flux generated in the first coil by the alternating current so that that part does not link with the second coil. An air gap is located to link with the second coil to create an inductor in that coil by flux in the second coil, and a capacitor is connected across the second coil to tune it to the fundamental frequency of the alternating current and substantially reduce harmonics in that current.
