摘要： In a discrete constant voltage control which carries out a voltage switch between different voltage levels, the present invention suppresses the influence of low-speed output detection voltage, carries out a high-speed transition under stable voltage conditions, and carries out a stabilized control in a constant voltage condition. The DC/DC converter of the present invention, in a discrete constant voltage control for voltage switching which switches different voltage levels and outputs the same, (i)by means of setting a gain A (A1, A2), suppresses the influence of an output voltage detection from following a command voltage and removing the detection output voltage Vo term, and (ii)by means of using an output voltage Vodet, which was estimated from a capacitor current, instead of the low-speed detection output voltage, suppresses the influence of the low-speed detection output voltage and suppresses the influence of a control from a delay time.

摘要： The purpose of the present invention is to achieve, during switching of voltage between a plurality of different voltages, high-speed control and a smooth and stable transition between high-side power and low-side power. A DC/DC converter is provided with a control unit and a main circuit including a switching circuit, and the control unit is provided with three control modes for transition between voltage levels, namely: a first mode in which a transition period between a pre-transition power level and a post-transition power level is implemented by means of constant-current control, a third mode in which a retention period for holding the voltages of the pre-transition power level and the post-transition power level is implemented by means of constant-voltage control, and a second mode in which a buffer period from the transition period to the retention period is implemented by means of constant-voltage control. The three modes are repeated in sequence so that a direct-current input is converted to and output as high-frequency pulses at a plurality of different voltage levels.

摘要： After setting a starting point A and an arrival point B, an operation management apparatus extracts a route traveling on the track R up to the arrival point B of the own train 10a. Subsequently, the own train 10a travels on the extracted route, trouble positions that hinder traveling are extracted, and among these trouble positions, a trouble position first existing is extracted as a trouble point S. Once only an occupied section T1 up to the trouble point S is locked in the route and the trouble point S is set, the own train 10a starts traveling in the occupied section T1. By repeating operation management control of route-locking only the occupied section T1 up to a trouble point S first existing on the route, and then traveling, unnecessary passage waiting is prevented based on the route-locking by another train 10.

摘要： Provided is multi-phase interleaving control in a power supply device, the control allowing the pulse widths ΔT of respective phases to overlap one another, so as to be adaptable to wideband pulse power control. In applying dead beat control to the multi-phase interleaving, constant current control is performed using combined current of the respective phase current values, and the pulse widths ΔT(k) is computed under this constant current control, thereby preventing variation of the pulse widths ΔT(k) between the phases, and achieving stable power control. Accordingly, the pulse power control becomes adaptable to wideband. Furthermore, wideband control is possible also in two-level pulse power control that performs control by switching at high frequency between High-level power and Low-level power.

摘要： In detecting the unignited state of plasma based on a reflected wave, false detection during a normal plasma ignition time is prevented so as to detect the unignited state during plasma abnormality. When a pulse output is supplied to a plasma load by pulse driving from an RF power source, the unignited state of plasma abnormality is detected on the basis of the continuous state of the reflected wave, whereby a total reflected wave generated in the unignited state during plasma abnormality is detected in distinction from the reflected wave generated in the normal ignited state. With this configuration, in detecting the unignited state by comparing a peak value of the reflected wave with a threshold, it is possible to prevent that a reflected wave generated in the normal ignited state is erroneously detected as the total reflected wave that is generated in the abnormal unignited state.

摘要： In radio frequency power source devices for delivering AC voltage outputs in antiphase with each other, having a configuration to divide the voltage output from a radio frequency output circuit into two, it is not possible to perform switching as appropriate, between different voltage values, high voltage and low voltage, resulting in that the voltage at an output end is reduced to have a half peak value of the voltage output of the radio frequency output circuit. There is provided a radio frequency power source device configured to change a voltage ratio between two output end voltages, by switching a connection state of a voltage divider that divides the radio frequency voltage, in such a manner that the radio frequency voltage is divided into voltage outputs in antiphase with each other with respect to ground potential, and high voltage and low voltage are delivered in switching manner. Switching of the connection state in the voltage divider enables selective delivery of voltage having different values, high voltage or low voltage, and by selecting and delivering high voltage for the time high voltage is required, reduction of the voltage output from the radio frequency output circuit is prevented.

摘要： A phase of the pulse control signal upon restarting is synchronized with the phase of the pulse control signal upon suspending, thereby suppressing fluctuations of output voltage in each phase of the inverter upon restarting and further suppressing fluctuations of voltage supplied to the load. Upon supplying DC power to a plasma generator, when arc discharge occurs in the plasma generator, supplying of the DC power is suspended to reduce damage on the electrodes and substrate, and further upon extinguishing of the arc discharge, supplying of the DC power is restarted. In suspending and resuming the DC output, the current flowing in the chopper upon suspending is held in the form of circulating current, and upon restarting the inverter, this circulating current is supplied to the load. Accordingly, it is possible to reduce a delay in supplying the DC power to the load, upon resuming the DC output.

摘要： In a voltage-type DC power supply provided with an inverter, current supply from the inverter to the load side is suppressed when arc is generated. DC output from the voltage-type DC power supply is suspended and resumed: upon suspending the DC output, the chopper is separated from the inverter, thereby suppressing excessive current to the load when arc is generated, allowing the arc to be extinguished at high speed, and holding the current passing through the chopper in the form of circulating current. Upon restarting the inverter, the circulating current being held is supplied to the load, thereby reducing a delay of supply of DC power to the load at the time of resuming the DC output from the voltage-type DC power supply.
