Method and apparatus to control an induction heating generator |
摘要 |
<p>The generator has a bridge circuit with two switches (T1,T2) in series across a supply, controlled so when one conducts the other is blocking. The common point is connected to an inductive load (22). The control detects negative voltage at the common point and deduces phase shift between voltage and current at the load, which is used in a negative feedback loop to control the switches.</p> |
