SWITCHING POWER SUPPLY CONTROL WITH PHASE SHIFT |
摘要 |
<p>A control system for a switching power supply shifts the phase of a PWM signal in response to a change in operating conditions. The phase may be shifted by resetting an oscillator that controls the PWM signal. Phase shift logic may include a sample-hold circuit that holds the value of an error signal when the PWM signal switches state. The held error signal may be compared to the real-time error signal, preferably with a user configurable offset. The output of the phase shift logic may be used to reset the oscillator.</p> |
