CYCLIC CONTROL CIRCUIT

摘要

A cyclic control circuit for a power factor controller uses cyclic action to switch a condenser on and off. The first and second up- counters (21a, 21b) set up the maximum coefficient as a reference and reset to zero when the counted value reaches the preset value; and the first and second decoders (24a, 24b) decode the counted value of the corresponding up-counter (21a or 21b).
