DC Apparatus of controling Voltage Balancer of Bipolar DC Microgrid and method therefor

摘要

The present invention is a voltage balance circuit control device and its control of the bipolar type DC microgrid relates to a method, and more particularly bipolar DC microgrids as that of the voltage balance circuit for solving the inequality of the voltage corresponding to the imbalance of the load or power, suggesting the construction of a controller for controlling this bipolar DC Micro It relates to the grid voltage balance circuit control unit and the control method thereof. The present invention is the voltage across the voltage balance circuit of the cathode-DC microgrids V p, and to measure the Vn obtained by subtracting the voltage Vn in the sum, the reference current generation unit which passes through a 1 PI controller generates a reference current flowing through the reactor; And the reference current generation unit based on current and voltage to produce a voltage change value through the PI controller of claim 2 the difference by comparing the measured value of the reactor current variation generation unit; A reference signal generator for generating a sum (V p + V n) as a reference signal by dividing the sum of the result of the voltage across the voltage Vn to the voltage variation value; And comparing the reference signal with the triangular wave signal in the pulse generating section for generating a PWM pulse considering the duty ratio; characterized in that it comprises a ;
