Title:
INVERTER FOR A MOTOR COMPRESSOR CONNECTED TO A PARALLEL POWER SOURCE AND A METHOD FOR DRIVING THE SAME
Document Type and Number:
WIPO Patent Application WO/2011/159031
Kind Code:
A2
Abstract:
Provided is an inverter for a motor compressor connected to a parallel power source, comprising: a first voltage conversion unit for receiving a voltage output from a first parallel power source and down-converting the same to a first voltage; a second voltage conversion unit for receiving a voltage output from a second parallel power source, which outputs a higher voltage than the first parallel power source and is connected in parallel with the first parallel power source, and for down-converting the same to a second voltage; a switch acting to pass or block the first voltage output from the first voltage conversion unit; and a comparator for feeding back, to the switch, a turn-off signal and transmitting the second voltage to a microprocessor power source if the first voltage and the second voltage are respectively input to a non-inverting terminal and an inverting terminal. Also provided is a method for driving the inverter. The present invention is devised in such a way that a microprocessor for controlling a motor compressor inverter can be driven with just the application of a low voltage, and, when a high voltage is applied, the low voltage is blocked and the high voltage is used to drive the microprocessor such that the drive power sources of the inverter of the motor compressor can be used selectively.
