摘要：

This paper introduces a microprocessor-based method to eliminate the dc current offset component in integral cycle-controlled RL loads. After choosing a suitable initial value of the triac (or thyristors) firing angle α (90° for best results), the microprocessor adjusts α closer to load power factor angle ø at every burst of conduction. A firing angle that is almost equal to ø is reached after few bursts. This eliminates the undesired dc current offset component. The use of the micrprocessor allows a simpler and more flexible solution to the problem than conventional techniques. © 1990 IEEE
