    CONVECTION (BLOWER) MOTOR OPERATION The convection (blower) motor is a variable speed convection motor, which operates from zero rpm up to 7000 rpm. The blower motor speed is controlled by a SP200 AC/Delta drive control. The speed of the motor is directly proportional to the applied low voltage to the SP200 AC./Delta drive control from the control circuit card.

  • Page 87 MAGNETRON CIRCUIT Overview of a microwave circuit The microwave circuit consists of a magnetron and a voltage doubler circuit. The voltage doubler consists of a special step–up transformer, a capacitor, a diode. In addition to the power circuitry in the magnetron the oven utilizes a filament transformer to pre-heat the magnetron filament before applying the high voltage to the anode.

  • Page 88: Magnetron High Voltage Power Supply

    Magnetron High Voltage Transformer (102093) The magnetron transformer is a ferro-resonant design which limits fault currents and minimizes HV TRANSFORMER OUTPUT VOLTAGE +(B) +2400 V 2400 2400 Current Flow CAPACITOR CHARGES ON POSITIVE VOLTAGE SWING 1. The Magnetron Transformer steps up the input voltage to approximately 2400 volts peak (4800 volts peak to peak).
  • Page 90 TurboChef Technologies, Inc. C Series Filament Transformer(102091) Background: The filament transformer is a step down transformer from 208-240VAC to about 4-5VAC. This voltage pre-heats the magnetron filament allowing it to be ready once the magnetron is energized by the high voltage transformer. This method in the industry is known as hot start and highly used to increase the life expectancy of the magnetron.
