| 摘要 |
<p>The present invention relates to an induction heating cooker (1) comprising a parallel resonant circuit (8) having an induction coil (6) and a resonant capacitor (7) connected in parallel to the induction coil (6), a power switch (9) that starts conducting in the closed position and provides the resonant capacitor (7) to be charged, providing the delivery of the energy stored in the resonant capacitor (7) to the vessel (K) by means of the induction coil (6) in the open position, a control unit (15) that determines the time the power switch (9) stays in the closed and open positions depending on the voltage value (Vce) of the collector node (13), a drive circuit (16) disposed between the output of the control unit (15) and the gate (12), that provides the power switch (9) to be driven with the required drive voltage (Vge) level, and wherein the power switch (9) is protected from high peak currents.</p> |
