New Description: [New Technology Field] This product provides a PWM to DC voltage circuit, especially a PWM to DC voltage with a corresponding duty cycle and output voltage adjusted to a linear value. [Prior Art] Pulse Wide Modulation (PWM) is a very effective technique for controlling the digital analog output of a microprocessor to oblique analog circuits. It is widely used in many fields from measurement and communication to power control and conversion. In short, PWM is a method of digitally encoding analog signal levels. With the use of a high resolution counter, the duty cycle of the square wave is modulated to encode the level of a particular analog signal. The PWM signal is still digital because at any given time, the full-scale DC supply is either completely (〇N) or completely absent (OF F ). The voltage or current source is applied to the analog load in a repeating pulse sequence of either (通N) or broken (〇F F). When the current is passed, the DC power is applied to the load, and when the power is disconnected, the power supply is disconnected. Any analog value can be encoded using pWM as long as the bandwidth is sufficient. In particular, it is applied to the DC voltage circuit, and the output voltage is controlled by the duty cycle of the pulse width modulation signal. However, most of the PWM-to-DC voltage circuits in the application power supply are usually in B-inch. The duty cycle of the PWM-to-DC voltage circuit corresponds to the output voltage, which usually assumes a nonlinear state, and this nonlinear state, This will result in a decrease in the efficiency of p WM at work. M326290 is how to solve the above problems and problems, the creators of the Maben case and the relevant manufacturers engaged in this industry are eager to study the direction of improvement. [New content] In the light of the above-mentioned shortcomings, the creators have collected relevant qualifications and considerations, and have designed and developed such new patents based on years of experience accumulated in the industry.
