Circuit for energy conservation

摘要

An improved circuit for automatically controlling energy to electrical energy consuming devices according to the well-known equation P_o=P_in-P_l+P_r ( 1 ) where P_o=Power output, P_in=Power input, P_l=Power losses, and P_r=Residual Power. Thus, the invention relates to a method and apparatus for obtaining a desired output power, P_o, from an electrical load by supplying sufficient pulse time modulation energy, P_in, to the device to replace only losses, P_l, and to maintain only the residual power, P_r, thus maintaining the desired Power output, P_o, and thereby conserving input energy, Pi_n, that would otherwise be wasted.
