Unique method of reducing losses in circuits using V2 PWM control |
摘要 |
A regulated power supply in which square wave output of a switching rectifier is applied to a filter comprises a series inductor and a parallel capacitor. This filter lacks a series resistor. The ramp signal is developed across a second capacitor in series with a first resistor, and in parallel with the rectifier output. An amplifier adds the ramp signal to a signal representing the error in the DC output voltage of the power supply, producing an output that is fed to a control circuit. The control circuit in response generates a voltage control signal that controls the switching of the rectifier.
