| Firstly, along with the world energy crisis’s gradual deepening, global variouscountries starts to devote in abundance to the new energy development research and theapplication; Secondly, the solar energy takes the green energy which one kind clean,highly effective, never dries up to receive people’s attention more and more; Finally,along with economic society’s development, the people are also getting higher andhigher regarding living conditions’ request, this also directly caused our country homeuse air conditioning’s use quantity to increase day after day, its power consumption alsostayed at a high level, but said as the product development simultaneously also has theconsiderable market prospect. Therefore, develops the solar cell and applies in the homeuse air-conditioning system, not can only alleviate the national electrical energy sourcescarce energy crisis question effectively, moreover can lead our country light to benddown industrial growing strong, thus it can be seen this topic’s deep research has thebroad market prospect and the scientific research value inevitably.This design needs to realize the function is, provides limitedly the solar cell board,and time-variable is limited the power, through the electrical energy converter technique,does not incorporate, does not increase the accumulator cell, applies directly inactuating the permanent torque loading characteristic air conditioning compressor,achieves the air conditioning refrigeration the goal. In other words, what this articleneeds to study is precisely in time-variable is limited under the power condition thepermanent torque loading control technology research.This article designs the frequency conversion velocity modulation control systemcontains has: The light bends down the battery board, the DC-DC transfer network, theIPM intelligence power module, the single-phase asynchronous motor, take themonolithic integrated circuit as the core controller. And, bends down the battery boardby the light to provide the time-variable direct current which the electro-optictransforms; The DC-DC transfer network completes the cocurrent pressure-rise andsimultaneously realizes the biggest power track, the control method uses theauto-adapted perturbation method of inspection, the pressure-rise part uses the PWMcontrol mode; The IPM intelligence power module completes the electric current toinvert, obtained will assign the frequency according to the instant generated outputcomputation the alternating current to provide for the single-phase asynchronous motoractuates the air conditioning compressor refrigeration, what the IPM intelligence powermodule uses is Mitsubishi Corporation’s PM50B4LB060module realizes, this module isbends down specially for the light single-phase inverts the IPM module which theelectricity generation invertor researches and develops, it has the simplified system, toenhance merits and so on system reliability; The frequency conversion velocitymodulation system uses the constant pressure frequency compared to the controlmethod, what the contravariant part uses based on DDS has the SPWM profile, the systems control part core to use is Ling Yang company’s16monolithic integrated circuitSPMC75F2413A realizes.Regardless of this topic has the positive significance from the feasibility and theusability, but still had some flaws, that is it cannot look like the present frequencyconversion air conditioning the temperature to control the air conditioning compressor’srefrigeration quantity equally through the manual surge chamber, in this design’s indoortemperature is not adjustable. This insufficiency, also will be precisely we in the futurein this domain a direction diligently. |
