Description

TECHNICAL FIELD [0001] The present invention relates to an output gain multi-extracting apparatus and a driving method thereof,

The present invention relates to an electronic circuit design, an electronic device and a device, and more particularly, because a characteristic inherent in a transformer that is apparent at a driving frequency causes a resonance phenomenon at a specific frequency in combination with a magnetic element, The present invention relates to an output gain multi-extracting apparatus for extracting a plurality of output gains, which is one of representative parameters that can detect self-resonance characteristics, and a driving method thereof.

In general, the switching device in the bridge is operated to provide a predetermined voltage output level in accordance with the "phase angle control of the duty cycle ". The trigger signal to the switching device detects a zero cross within the phase of each AC signal and generates a corresponding trigger signal (generally after a delay in accordance with a predetermined phase angle in the AC signal and with the required DC output level ) Controller. More specifically, in a conventional system, when a zero cross is detected at a particular phase, the controller is delayed by a time period in accordance with the duty cycle required (in turn, according to the required output voltage level).

The delay is usually caused by a one shot or conventional timing circuit. For example, the capacitor is charged with current when the voltage across the capacitor exceeds the reference voltage, and the capacitor is discharged if a trigger on the SCR associated with the phase occurs. Depending on the trigger signal, the SCR is activated (conductive) past the point where the current becomes zero, and until the next trigger signal becomes nonconductive. The cycle is repeated in response to the next zero cross of the appropriate polarity.

In a semi-control system, the phase angle control of the duty cycle is influenced by the selective actuation of the switching device controlled during its associated half-cycle of the AC signal, during the entire (opposite polarity) half- The diode portion is conductive.

Thus, the range of output signals that can be generated from a given AC signal level (and thus the range of the input AC signal) is limited as compared to the prior control system.

In addition, industrial and medical high-voltage pulse output devices are capable of outputting relatively high voltages, generally ranging from several hundred kHz to several Mhz, ranging from several tens of kV to several kV of various output frequencies, but the output frequency must be varied or fixed In this case, when a single output transformer is used, there is a problem that the output gain becomes lower as the frequency increases due to the inherent impedance of the transformer.

That is, the division area divided into N (M + 1) pieces from the secondary side coil is a separation interval between any one of the M tap lines and the secondary coil, or another separation interval between any one of the M tap lines and another I can.

This is because the separation of the transformer 100 according to the present invention is accomplished by linearly winding the secondary coil so that there are N number of the secondary windings D _A1 to D _AN using M tap lines, (See Figure 2).

In addition, the M tap lines extending from the secondary coil of the transformer 100 may be connected to a plurality of switches in a 1: 1 matched format, respectively.

2, the controller 200 controls the period of the clock pulse wave with the periodic control signal or numerically controls the supply voltage with the supply power control signal to drive the relay unit 500, and the relay unit 500 And a plurality of switches connected in series.

In other words, the relay unit 500 receives a drive command from the controller 200 and supports a plurality of switches selectively on and off by using any one of a mechanical relay, a pressure relay, and an optical relay The state plays a role.

The controller 200 activates the transformer 100 by the number of times when a plurality of switches are turned on to output the first winding ratio or M + 1 second winding ratio N1 / M3. Where N = M + 1)

The operation unit 300 extracts a first gain value or M + 1 second gain values expressed in units of dB [decibels] by logarithm conversion of the first winding ratio or the M + 1 second winding ratios.

When the plurality of switches are selectively turned on according to the predetermined order, the calculating unit 300 calculates the (M + 1) th second winding ratio representing the ratio of the M + 1th winding number to the first winding number (M + 1) -th second winding ratio, which is a ratio to the M-th third winding number with respect to the first winding yarn, is logarithmically converted to obtain the second M + Is obtained.

Accordingly, as shown in FIG. 4, the display unit 400 displays the M + 1th frequency region representing the (M + 1) th second gain value and the Mth frequency region representing the Mth second gain value Expressed on a graph or a separate graph.

The (M + 1) -th frequency domain is displayed in a relatively higher band than the M-th frequency domain.

The controller controls the period of the clock pulse wave by the periodic control signal or drives the relay part of the relay part by numerically controlling the supply power value with the supply power control signal so that any one of the plurality of switches connected to the relay part is selectively turned on - turn off (S150, S160).

In other words, in the output gain multi-extractor, the non-connected relay unit receives the drive command (which will be referred to as the control command signal issued by the periodic control or the numerical control) from the controller to receive the thermal relay, And an optical relay, so that a plurality of switches are selectively turned on and off.

In a circuit design according to an embodiment of the present invention, the M tap lines extending from the secondary coil of the transformer will each be connected in a 1: 1 matched format with multiple switches.
