<p>The present invention is to provide an effective newly designed circuit which can output graded multi-voltage, and further combine with linear or chopped solid switch member so as to attain series and parallel switch to adjust its output value when the voltage changes because of accepting solar quality changes or attain the non-sparkle multi-voltage switching and low ripple-wave PWM voltage output of graded linear or chopped wave and further feedback the limited current or set voltage output adjustment function.</p> |
