Definitions

  • a microwave oven apparatus comprising:
  • a high frequency oscillator incuding a magnetron, for always oscillating at a substantially constant high frequency and connected to the output of said controlled rectifying circuit;
  • a triggering circuit coupled to said pulse signal generator and to said controlled rectifying circuit for triggering said controlled rectifying circuit upon receipt of pulse signals from said pulse signal generator to intermittently energize said high frequency oscillator, for controlling the net DC energy supplied to said magnetron from said power source while the oscillating frequency of said high frequency oscillator remains substantially constant.
