| 摘要 |
The present invention is through the power control unit, which is connected with the voltage-dividing load in parallel, to perform shunt regulation for the current passing through the voltage-dividing load; in which the methods of the shunt regulation by the power control unit includes using the power control unit to perform shunt regulation of PWM, shunt regulation of conductive phase angle, or shunt regulation of switch type turn-on or cut-off, or regulating the impedance of the power control unit.
