INDUCTION HEATING APPARATUS WITH ALTERNATING SWITCHING MEANS |
摘要 |
<p>INDUCTIVE HEATING APPARATUS Inductive heating apparatus includes serially connected first and second transistors which are alternately caused to conduct by a control circuit. A resonant circuit including an induction heating coil and a capacitor is connected in parallel with the second transistor. When the first transistor conducts a first current flows to charge the capacitor and when the second transistor conducts a second current flows in the resonant circuit to discharge the capacitor. The control circuit produces a turn-off signal to the conducting transistor before the current through the conducting current falls to zero and also produces a turn on signal to the nonconducting transistor when the current through the conducting transistor reaches zero.</p> |
