DETAILED ACTION
Notice of Pre-AIA or AIA Status
The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA .
This action is in response to an application filed on 03/25/2024.
Claims 1-7 are pending for examination.
Claim Objections
Claim 1 recite the limitation "a capacitor" in lines 8-9. There is insufficient antecedent basis for this limitation in the claim.
Claim Rejections - 35 USC § 102
The following is a quotation of the appropriate paragraphs of 35 U.S.C. 102 that form the basis for the rejections under this section made in this Office action:
A person shall be entitled to a patent unless –
(a)(1) the claimed invention was patented, described in a printed publication, or in public use, on sale, or otherwise available to the public before the effective filing date of the claimed invention.
Claims 1, 7 and 8 are rejected under 35 U.S.C. 102 (a) (1) as being anticipated by Ogura et al. (JP 2014212584 A and Ogura hereinafter – English Machine Translation is attached).
As to Claim 1, Ogura in its teachings as shown in Fig.1-6 disclose a power conversion apparatus (2) that supplies alternating-current power to a motor (5), the motor driving a load (6), the power conversion apparatus (2) comprising:
a converter (42) rectifying a power-supply voltage applied from an alternating-current power supply (41);
a capacitor (43) connected to an output end of the converter;
an inverter (3) connected across the capacitor; and
a control device (1) controlling an operation of the inverter, wherein
the control device performs a first control (adding a correction command Idsin* to a d-axis current command Id* via adder 19d that outputs Id**- see [0030]) to output of reducing a pulsatile component of a capacitor (43) output current output from the capacitor to the inverter when the load is driven (The DC power supply 4 for supplying DC power (voltage) to the inverter 3 has an AC power supply 41, a diode bridge 42 for rectifying AC to DC, and a smoothing capacitor 43 for suppressing pulsation contained in the DC power supply- see [0017]),
the first control is control of causing the motor to generate a loss, and the loss that the motor is caused to generate is performed by using an excitation current (if the d-axis current increases by adding the correction command to the d-axis current command, a loss occurs in the electric motor due to the increase and the loss occurs in the electric motor due to the increase in the d-axis current (excitation current) by the first control – see also [0071] - [0072] and [0081] – [0087]).
As to Claim 7, Ogura disclose a motor drive apparatus comprising the power conversion apparatus according to claim 1 (see [0011]).
As to Claim 8, Ogura disclose a refrigeration cycle application apparatus comprising the power conversion apparatus according to claim 1 (a compressor provided in a refrigeration system or a refrigeration system- see [0090]).
Allowable Subject Matter
Claims 2-6 are objected to as being dependent upon a rejected base claim, but would be allowable if rewritten in independent form including all of the limitations of the base claim and any intervening claims.
Conclusion
The prior art made of record and not relied upon is considered pertinent to applicant's disclosure (US 2013/0300327 A1: A DC link is provided, which includes a capacitor connected in parallel to an output of a converter circuit, and outputs a pulsating DC link voltage. An inverter circuit is provided, which converts an output of the DC link to AC by switching, and supplies the AC to a motor connected thereto. A controller is provided, which controls switching of the inverter circuit so that motor currents pulsate in synchronization with pulsation of a power-supply voltage. The controller controls the switching of the inverter circuit in accordance with a load of the motor or an operational state of the motor, and reduces pulsation amplitude of the motor currents – [Abstract]).
