Problems solved by technology

However, as the capacity of the busbar capacitance decreases, the fluctuation of the busbar capacitance will also increase with the increase of the load when the compressor is running. Running steadily, losing steps, and eventually leading to out-of-control shutdown

Embodiment Construction

[0027] The embodiments of the present invention are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The embodiments of the present invention are described in detail below.

[0028] In the embodiment, such as figure 1 Shown is the hardware principle diagram of the air conditioner according to the embodiment of the present invention. Due to the decrease in the capacity of the bus capacitor C0, when the compressor is running, as the load increases, the fluctuation of the bus capacitor C0 will also increase. The lowest voltage value of C0 fluctuating is lower than the required bus voltage for compressor operation, which will cause the compressor to fail to run stably, and even cause out-of-control shutdown. Therefore, the embodiment of the present invention adopts a boost power factor correction circuit to adjust the power The duty cycle of the factor correction circuit is used to increase the voltage value of the bus cap...

Abstract

The invention discloses a method for controlling the bus voltage of an air conditioner, the air conditioner and a storage medium. The method for controlling the bus voltage of the air conditioner comprises the following steps of obtaining a phase current value of an air conditioner compressor, and obtaining the voltage values of two ends of an air conditioner bus capacitor; calculating a requiredbus voltage value of the compressor according to the phase current value of the compressor, and calculating lowest voltage values of the two ends of the bus capacitor in a power supply voltage periodaccording to the voltage values of the two ends of the bus capacitor; and controlling a power factor of the air conditioner and correcting the duty ratio of a circuit according to the required bus voltage value and the lowest voltage values. The method can improve the voltage value of the bus capacitor and ensure that the compressor can operate stably.

Description

Technical field [0001] The present invention relates to the technical field of air conditioners, in particular to a method for controlling the bus voltage of an air conditioner, a non-temporary computer storage medium and an air conditioner. Background technique [0002] The variable frequency drive board has a large bus energy storage capacitor configuration, which is often connected by multiple high-voltage bus energy storage capacitors in parallel. Although this method can meet the torque output of the compressor at any time, the high-voltage bus capacitor has a higher cost and takes up the area of ​​the PCB board. Larger, unable to miniaturize, high power density design. [0003] In related technologies, some schemes adopt to reduce the capacity of high-voltage bus energy storage capacitors, for example, from the original three 680uF / 450V to three 470uF / 450V, and from the original three 680uF / 450V to two 680uF / 450V , From the original two 680uF / 450V to two 470uF / 450V, from the...
