Problems solved by technology

[0002] When various devices or components operate, no matter they generate signal sources or serve as loads, they need to be supplied with power to make them play their due role; however, the voltages required by the aforementioned devices or components are often different from each other. Please refer to figure 1 As shown in a known technology, when a pulse width modulation signal (PWM) is in the duty cycle (Duty Cycle), the storage device C is charged through the resistor R, and when the PWM signal is in the non-duty cycle, the storage Electric part C discharges until the pulse width modulation signal becomes Hi (i.e. duty cycle) and begins to charge again; therefore, the overall output voltage of this prior art is roughly fixed
[0003] However, in practical applications, the aforementioned technologies are often unable to provide various voltages as required
