2.2. Inverter power supply circuitThe Inverter Power Supply circuit powered from the linevoltage, 120V 60Hz AC input supplies 4,000V DC to themagnetron tube, and functions in place ofthe H.V. transformer,the H.V. capacitor and H.V. diode. 1. The AC input voltage 120V 60Hz is rectified to DC voltage

immediately. 2. DC voltage will be supplied to the switching devices called

IGBT. These devices are switched ON-OFF by the 20 to 40kHz PWM (pulse width modulation) signal from themicrocomputer in the DPC.

3. This drives the High voltage transformer to increase voltageup to 2,000V AC.

4. Then the half-wave doubler voltage rectifier circuit,consisting of the H.V. diodes and capacitors, generates thenecessary 4,000V DC needed for the magnetron.

5. Output power of the magnetron tube is always monitored bythe signal output from the current transformer built into theinverter circuit.

6. This signal is fed back to the microcomputer in the DPC todetermine operating conditions and output necessary tocontrol PWM signal to the Inverter Power Supply for controlof the output power.

2.3. Inverter defrostWhen the Auto Control feature is selected and the Start buttonis tapped: 1. The digital programer circuit determines the power level and

cooking time to complete cooking and indicates theoperating state in the display window. Table shows thecorresponding cooking times for respective serving bycategories.

Inverter Turbo DefrostSELECTED WEIGHT COOKING TIME

1.0 LB 5 min.28 sec.

2. When cooking time in the display window has elapsed, theoven turns off automatically by a control signal from thedigital programmer circuit.

2.4. Sensor cooking (Only forsensor models)

Auto sensor cooking without setting a power level or selectinga time. All that is necessary is to select an Auto SensorProgram before starting to cook.Understanding Auto Sensor Cooking

As the food cooks, a certain amount of steam is produced.If the food is covered, this steam builds up and eventuallyescapes from the container. In Auto Sensor Cooking, acarefully designed instrument, called the humidity sensorelement, senses this escape of steam. Then, based uponthe Auto Sensor Program selected, the unit willautomatically determine the correct power level and theproper length of time it will take to cook the food.

NOTE:Auto Sensor Cooking is successful with the foods andrecipes found in the Auto Sensor Cooking Guide.Because of the vast differences in food composition,items not mentioned in the Cooking Guide should beprepared in the microwave oven using power selectand time features. Please consult Variable PowerMicrowave Cookbook for procedures.

NN-SD297SR

Explanation of the Auto Sensor Cooking process 1. T1 time The total amount of time it takes the microwave

oven to switch to T2 time. 2. T2 time When the steam escapes from the cooking

container placed in the oven, the humidity sensordetects it and the microprocessor calculates the balanceof cooking time. This T2 time is then shown in thedisplay and begins counting down.Balance of cooking time (T2 time)The balance of cooking time which is called T2 time,can be calculated by the following formula.T2 time (in sec.) = T1 time X K factor

NOTE:The coefficient K is programmed into themicroprocessor memory and they are listed in thefollowing tables along with the P1 and P2 powers.

NOTE:When "More" or "Less" button is selected, the K factorvaries resulting in T2 time to be increased or decreased.

Example of calculating the T2 timeExample 1: If the T1 time is measured to be 2 minutes and40 seconds, and the Auto program selected is Oatmeal:T2 = T1 × K= 2 min. and 40 sec. × 0.1= 160sec. × 0.1= 16 sec.
