ANTI-CONDENSATION CONTROL SYSTEM

摘要

System and methods for providing anti-condensation system are disclosed. A relative humidity (RH) sensor signal from a sensor on or near a control surface is received. An AC power input is received. A phase of the AC power input is modulated at least partly in response to the sensor signal in such a manner that a phase-modulated AC power output provided to a heater is a) substantially constant at a first power level (P1st) in a low RH region ranging from 0% RH to a first RH (RH1), b) varying as a function of the sensor signal from P1st to a second power level (P2nd) in an intermediate RH region ranging from RH1 to a second RH (RH2), and c) substantially constant at P2nd in a high RH region beginning at RH2.
