Abstract
PURPOSE: To improve efficiency by balancing output currents of respective pulse- width modulation system switching regulators without reference to the circuit system of switching regulators when operating the switching regulators in parallel.
CONSTITUTION: Output voltages Vo of a plurality of pulse-width modulation system switching regulators SW-Regsl whose input-output terminals are connected to a common bus and constant voltage Vref from reference voltage generating circuit 15 are amplified by error amplifier 16. Then, this system consists of constant voltage control part 2 supplying the 1st control voltage Vc to each SW-Reg, synchronizing pulse generating circuit 4 generating synchronizing pulses A synchronizing the timing of the switching of each SW-Reg, and load 3. In this case, the mean peak value of voltage pulse B is nearly shown in the linear function of the output voltage, and negative DC voltage Vx obtained by rectifying voltage pulse C by smoothing circuit 9 is also shown nearly in the linear function of the output current. Voltages Vx, Vo, Vref, and Vc are mixed by mixing circuit 10 to obtain the 2nd control voltage V'c as shown by equation (1).
