POWER CONVERTING APPARATUS, HEAT PUMP APPARATUS, AND AIR CONDITIONER - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240048066 titled 'POWER CONVERTING APPARATUS, HEAT PUMP APPARATUS, AND AIR CONDITIONER
Simplified Explanation
The patent application describes a power converting apparatus that includes a rectifier, capacitor, reactor, load, and control unit. The rectifier converts alternating-current power output from a power supply into direct current. The capacitor is connected to the output end of the rectifier. The reactor is placed between the power supply and the capacitor. The load is connected across the capacitor. The control unit reduces the charging and discharging current of the capacitor by controlling the operation state of the load, causing power pulsation in the power consumed by the load. The inductance value of the reactor is defined based on the maximum and minimum values of the output voltage of the rectifier, the direct-current component of the load's output power, the number of phases of the power supply, and the angular frequency of the power supply.

Original Abstract Submitted
a power converting apparatus includes: a rectifier that rectifies alternating-current power output from an alternating-current power supply; a capacitor provided at an output end of the rectifier; a reactor provided on a path from the alternating-current power supply to the capacitor; a load connected across the capacitor; and a control unit that reduces a charging and discharging current of the capacitor by controlling an operation state of the load such that power pulsation occurs in power to be consumed by the load, wherein a range of an inductance value of the reactor is defined by use of a maximum value of an output voltage of the rectifier, a minimum value of the output voltage of the rectifier, a direct-current component of output power of the load, a number of phases of the alternating-current power supply, and an angular frequency of the alternating-current power supply.
