The invention discloses a direct current boost power source for a direct current boost inverter compressor. The direct current boost power source for the direct current boost inverter compressor comprises a battery, a boost module, a rectifying module, a power management module, an output module and a switchover module. The power management module is connected with the battery. The rectifying module is connected with the output module. The switchover module is connected with the power management module. According to the direct current boost power source for the direct current boost inverter compressor, a boost mode of a direct current power source of the battery is adjustable, however the voltage of the battery changes, the output direct current voltage can satisfy the requirement for the direct current voltage which is needed for normal operation of the direct current boost inverter compressor, conversion efficiency is high, stability and reliability are good, and energy consumption is low. The direct current boost power source for the direct current boost inverter compressor is mainly used in the boost technology of the direct current boost inverter compressor.
Description
technical field [0001] The invention relates to the technical field of step-up of a DC step-up frequency conversion compressor, in particular to a DC step-up power supply used in a DC step-up frequency conversion compressor. Background technique [0002] With the improvement of living standards, air conditioners have become more and more popular. Car air conditioners are not uncommon for a long time, but at present, car air conditioners are directly driven by car power, and when the car power is turned off, the air conditioners cannot be used. This brings the problem of cooling after turning off the on-board power to some large trucks. Compared with traditional fixed-speed air conditioners, AC inverter air conditioners, and even ordinary DC inverter air conditioners, the full DC inverter air conditioner has incomparable advantages. The full DC inverter air conditioner can better adjust the comfortable temperature in the car, saving Electric effect is good. Since the batte...
