The second amplifier A106 in the standby state is driven to operate the transistor Q102, and the transistor Q102 drives the relay circuit 534.

Thereafter, the relay circuit 534 drives the filtering unit 54 to remove noise of the control signal.

As shown in the following figure, the filtering unit 54 driven by the relay circuit 534 and removes the noise receives a driving signal from the relay circuit 534, the signal input circuit 541 for receiving a control signal A main filter circuit 542 connected to the signal input circuit 541 to remove noise included in the control signal, and a sub filter connected to an output terminal of the main filter circuit 542 to remove residual noise included in the control signal. Circuit 543.

More specifically, the signal input circuit 541 is connected to the relay circuit 534 of the filter driver 53 to receive a driving signal for driving the

filtering circuits

542 and 543. Also receives a control signal. In addition, when noise is not detected in the control signal, an output terminal is provided so that the control signal can be directly output without passing through the

filtering circuits

542 and 543.

For example, the signal input circuit 541 includes a selector such as a multiplexer. The signal input circuit 541 is an input terminal of the main filter circuit 542 or an output terminal for outputting a control signal, that is, two paths are selected based on a driving signal. It is preferably provided to transmit the control signal. Although illustration and detailed description of the drawings related to the signal input circuit 541 is omitted, those skilled in the art will be able to understand and infer any number.

Next, the main filter circuit 542 includes a forward diode D105 connected to an output terminal of the signal input circuit 541, a resistor R127 and a capacitor C114 connected in series and parallel to each other, and a capacitor connected in series thereto. C115) and forward diode D106.

Referring to the operation process, the forward diode D105 blocks the flow of current in one direction, blocks the current from flowing back from the main filter circuit 542 to the signal input circuit 541, and the resistor R127 connected in parallel with each other. The capacitor C114 removes noise included in the control signal. The capacitor C115 and the diode D106 connected thereto further increase the noise removal efficiency.

Next, the sub-filter circuit 543 connected to the output terminal of the main filter circuit 542 to remove residual noise includes an amplifier A107, first and second transistors Q103 and Q104, and a biased resistor ( R128 to R135) and capacitors C116 and C117.

Referring to the sub-filter circuit 543, three resistors R128, R129, and R130 are connected to the positive terminal of the amplifier A107, and one R128 is an output terminal of the main filter circuit 542. Are connected in series, and the other two R129 and R130 are connected in parallel thereto, and the positive terminal of the amplifier A107 is connected between two resistors R129 and R130.

A capacitor C116 and two resistors R131 and R132 and a reference voltage input terminal Sref connected to each other in parallel with the capacitor C116 are connected to the negative terminal of the amplifier A107. One R131 is connected in series to the reference voltage input terminal, the other R132 is connected to ground, and the capacitor C116 is connected in parallel between two resistors R131 and R132.

In addition, first and second transistors Q103 and Q104 are connected to the output terminal of the amplifier A107. A resistor R133 is provided between the first transistor Q103 and the amplifier A107 to output the amplifier A107. The voltage is dropped to generate an operating point for driving the first and second transistors Q103 and Q104.

The first transistor Q103 is an npn transistor, the base is connected to the output terminal of the amplifier A107, the emitter is connected to ground, and the collector is connected to the base of the second transistor Q104.

The second transistor Q104 is a pnp transistor. The base is connected to the collector of the first transistor Q103 as described above, the collector is connected to ground, and the emitter is connected to the control signal output terminal.

In particular, between the second transistor (Q104) and the output terminal of the control signal is provided with two resistors (R134) (R135) arranged in series and a capacitor (C117) connected in parallel between the two.

Referring to the operation of the sub-filter circuit 543, first, the two resistors (R131) (R132) and capacitor (C116) provided at the (-) terminal of the amplifier A107 is a signal input from the reference voltage input terminal (Sref). Generate a reference voltage through. This reference voltage serves as a reference for noise removal, and any voltage level higher or lower than the reference voltage is regarded as noise and removed.

Next, three resistors R128, R129, and R130 provided at the positive end of the amplifier lower the voltage level of the control signal passed through the main filter circuit 542 to be comparable with the reference voltage. It may be omitted depending on the output voltage level of the circuit 542.

The amplifier A107 operates as a comparator, and compares the reference voltage level with the level of the control signal to check whether there is residual noise.

In addition, the first transistor Q103 and the second transistor Q104 of the subfilter circuit 543 increase in voltage when the control signal is momentarily higher or lower than the reference voltage including residual noise (generally in case of noise). In this case, the capacitor C117 is charged with a voltage that is raised by the noise and the voltage level of the control signal dropped by the capacitor is equal to the reference voltage level.

After that, when the voltage level of the control signal corresponds to the reference voltage level, the first transistor Q103 and the second transistor Q104 are turned off, and then the voltage stored in the capacitor C117 is connected through the resistor R135 connected in parallel. It is discharged and restored to its original state.

The configuration of the filtering unit 54 primarily removes the noise through the main filter circuit 542, and removes the remaining residual noise and the momentarily introduced noise through the sub filter circuit 543, thereby completely eliminating noise. By outputting a clean control signal that is not included, it provides an effect of preventing malfunction and failure of each component.

Of course, it is also possible to include only the filtering unit 54, but the level adjusting unit 51 is to set the voltage level of the stable signal, so that the control signal can be maintained at a constant level, and controlled by the noise detector 52 By amplifying the signal to detect noise more sensitively, the filter driving unit 53 allows the driving of the filtering unit 54 to be selectively operated according to the noise detection, so that the life of the filtering unit 54, in particular the filtering unit The life of the capacitors C114 to C117 provided at 54 is extended.

In addition, the fact that the filtering unit 54 is not always driven and is selectively driven according to whether noise is detected may provide a remarkable effect in reducing power consumption.
