- the R phase and the T phase are connected to the converter 8 via the first relay 52.
- a current limiting circuit 8c including a second relay 84 and a current limiting resistor 85 is connected in parallel with the T-phase first relay 52.
- the converter 8 includes a rectifier circuit 8 a made up of six diodes 81 and a smoothing circuit 8 b made up of a reactance 82 and an electrolytic capacitor 83.
- the inverter 9 converts the direct current output from the converter 8 into alternating current of an arbitrary frequency and supplies it to the motor of the compressor 11 .
- the inverter 9 is driven by a drive circuit 41, and the drive circuit 41 is controlled by an INV control microcomputer 6. Further, the INV control microcomputer 6 detects the voltage Vpn between the terminals of the electrolytic capacitor 83 via the voltage detection means 42.
- the second relay 84 When the power is turned on, the second relay 84 is turned on prior to the first relay 52, and the electrolytic capacitor 83 is gradually charged by the current limiting resistor 85. If the first relay 52 is turned on while the electrolytic capacitor 83 is empty or insufficiently charged, an inrush voltage is applied to the electrolytic capacitor 83 and the electrolytic capacitor 83 may be damaged. Therefore, the first relay 52 is turned on after the electrolytic capacitor 83 is appropriately charged.
- the charging time varies depending on the model of the air conditioner 1, but is charged for 4 seconds in this embodiment.
- Control device 4 is provided with a temperature rise suppression logic for determining a short circuit between PN (between the terminals of electrolytic capacitor 83) at an early stage and preventing abnormal heat generation of current limiting resistor 85 in advance.
- a temperature rise suppression control logic of the current limiting resistor 85 will be described with reference to the drawings.
- FIG. 4 is a flowchart of the temperature rise suppression control of the current limiting resistor 85.
- the control microcomputer 5 turns on the second relay 84 (Sl), and transmits a Vpn detection command flag to the INV control microcomputer 6 (S2).
- the INV control microcomputer 6 receives the Vpn detection flag (S21), operates the timer, and measures the time tl when the second relay 84 is turned on and the force has passed (S22).
- the INV control microcomputer 6 determines whether or not tl has reached 0.3 seconds (S23), and if Yes, determines whether or not Vpn is 10V or less (S24) o S24 If Yes, there is a high possibility that the terminals of the electrolytic capacitor 83 are short-circuited, so an abnormality flag and a standby request flag are transmitted to the control microcomputer 5 (S25). N in S24. Then go to A. The flow from S21 to S25 is called first voltage detection control.
- the control microcomputer 5 receives the abnormality flag and the standby request flag transmitted from the INV control microcomputer 6 (S3), and turns off the second relay 84 (S4). And the number of abnormal flag reception Start counting Nl (S5). Then, it is determined whether or not N1 is less than 2 (S6). If Yes, the timer is operated to measure t2 (S7). Then, it is judged whether t2 has reached 600 seconds (S8). If Yes, the process returns to SI. If the determination in S6 is No, the control microcomputer 5 determines that there is a failure that causes an abnormality in the voltage across the terminals of the electrolytic capacitor 83, and displays an abnormality. The flow from S3 to S8 is called retry control.
- the microcomputers 5 and 6 of the control device 4 turn on the second relay 84, and if the force is also less than 0.3 V, the second relay 84 is turned on again after 600 seconds. Operate and detect Vpn after 0.3 seconds. If Vpn detected for the second time is 10V or less, it is determined that the short circuit is between PN (between terminals of electrolytic capacitor 83), operation is stopped, and an error is displayed. If an error is displayed, retry control will not resume unless manual return (remote control return) is performed by the remote control device 4a. In this way, the temperature rise of the current limiting resistor 85 is suppressed.
- control device 4 continues to charge electrolytic capacitor 83.
- the control device 4 can turn on the first relay 52 and start the motor of the compressor 11.
- an inrush voltage is applied to the electrolytic capacitor 83 when the first relay 52 is turned on.
- Capacitor 83 may be destroyed. Therefore, before turning on the first relay 52, the control device 4 needs to detect the voltage Vpn between the terminals of the electrolytic capacitor 83 and determine whether or not the voltage value is insufficient. In the control device 4, the undervoltage detection control logic of the electrolytic capacitor 83 is set.
- FIG. 5 is a flowchart of the undervoltage detection control of the electrolytic capacitor 83. If it is determined in S24 of the temperature rise suppression control of the current limiting resistor 85 that “Vpn exceeds 10V”, the microcomputer 5 counts the time tl when the second relay 84 is turned on and the force has elapsed. Continuing from microcomputer 6, it is determined whether or not tl has reached 4 seconds (S11). If YES in S11, the second relay 84 is turned off (S12), and the Vpn detection command flag is sent to the INV control microcomputer 6. (S13). The INV control microcomputer 6 receives the Vpn detection command flag (S31), and determines whether Vpn is 16 OV or less (S32).
- the control microcomputer 5 receives the abnormality flag and the standby request flag transmitted from the INV control microcomputer 6 (S14), and starts counting the number N2 of reception of the abnormality flag (S15). It is determined whether N2 is less than 4 (S16). If Yes, the timer is activated and t3 is counted (S17). Then, it is determined whether t3 is 180 seconds or more (S18). If Yes, the process returns to SI. The reason why the standby time of 180 seconds is provided in S18 is to sufficiently discharge the electric charge in the electrolytic capacitor 83. If the determination in S16 above is No, display an error. The flow from S13 to S18 is called retry control.
- the microcomputers 5 and 6 of the control device 4 turn on the second relay 84 and turn off the second relay 84 four seconds after the force is turned on, and detect Vpn. If the Vpn is less than 160V, it is determined as abnormal and the second relay 84 is turned on again 180 seconds later. If it is determined that there is an abnormality four times in succession, it is determined that the electrolytic capacitor 83 has failed, the operation is stopped, and an abnormality is displayed. If an error is displayed, the retry control will not resume unless the remote control device 4a is used for manual return (remote control return). In this way, the failure of the electrolytic capacitor 83 is determined and appropriate measures are taken.
- the control microcomputer 5 turns on the second relay 84 until the preset charging time (4 seconds) ends, and the electrolytic capacitor 83 is connected via the current limiting resistor 85. Charge gradually. Then, when the charging time ends, second voltage detection control for detecting the voltage across the terminals of the electrolytic capacitor 83 is performed. Further, the control microcomputer 5 and the INV control microcomputer 6 perform the first voltage detection control.
- the first voltage detection control is a control for detecting the voltage across the terminals of the electrolytic capacitor 83 when the first time (0.3 seconds) shorter than the charging time has elapsed since the second relay 84 was turned on. is there.
- Short circuit between terminals of electrolytic capacitor 83 occurs Then, since the voltage between the terminals of the electrolytic capacitor 83 when the first time has elapsed does not reach the reference value, the short circuit between the terminals of the electrolytic capacitor 83 is detected at an early stage by the first voltage detection control. For this reason, appropriate measures are taken before adversely affecting peripheral components. In addition, if the voltage between the terminals of the electrolytic capacitor 83 detected in the first voltage detection control satisfies the reference value set in advance, the second relay does not wait for the end of the charging time. Since 84 is turned off, the time during which the overvoltage is applied to the current limiting resistor 85 is shortened, and abnormal heat generation of the current limiting resistor 85 due to the overvoltage is avoided.
- the control device 4 determines that an abnormality has occurred and repeats the first operation. 1 Retry control for voltage detection control is executed. If the voltage between the terminals of the electrolytic capacitor 83 detected by the first voltage detection control is not normal, the second voltage detection control is not executed. For this reason, useless energization to the current limiting resistor 85 is suppressed, and the thermal influence on peripheral components due to the temperature rise of the current limiting resistor 85 is mitigated.
- the abnormality determination starts, and if the number of abnormality determinations reaches a preset value, it causes an abnormality in the voltage across the terminals of the electrolytic capacitor 83. It is determined that there is a failure. For this reason, erroneous determination due to noise can be avoided, and the reliability of determining an abnormality is increased. Furthermore, when it is determined that the space between the terminals of the electrolytic capacitor 83 is abnormal, the retry control is not executed. For this reason, unnecessary repeated retries are avoided, and unnecessary current supply to the current limiting resistor 85 is suppressed, and the thermal influence on peripheral components due to the temperature increase of the current limiting resistor 85 is mitigated.
- This control device 4 further includes a remote control device 4a, and is connected to the terminal of the electrolytic capacitor 83. If it is determined that the interval is abnormal, an abnormality display is performed. The retry control is not executed until the abnormality display is canceled by the remote operation device 4a. For this reason, since the operation is not performed until the cause of the abnormality between the terminals of the electrolytic capacitor 83 is resolved, safety is improved.
- the above-described embodiment is effective for a converter circuit for a single-phase AC power source, which is intended for a converter circuit for a three-phase AC power source.
- control microcomputer 5 and the INV control microcomputer 6 may be handled separately, and the force control microcomputer 5 and the INV control microcomputer 6 may be unified into one common control microcomputer. .
- the reactance 82 is arranged in the smoothing circuit 8b of the converter 8, but it may be omitted.
- the power connected to the converter 8 as the inverter 9 and the compressor 11 may be other devices.
- an abnormality such as a short circuit between terminals of an electrolytic capacitor in a converter can be detected at an early stage, which is useful for a control device.
