In these ovens, line voltage is applied to the filament and highvoltage windings simultaneously. This type of power supply will always produce a few seconds delay between the time the start button is pressed and when the magnetron actually starts emitting microwaves. This type of power supply is called a `coldstart' power supply (see Fig. 4.4) because the such supplies are operated "coldstart": i.e. when the line voltage is applied to the power transformer high voltage appears immediately while the filament temperature and microwave power lag in starting by about l2 s. This delay may be smaller at the beginning.of life but as the end of life approaches this delay may be considerably greater, e.g.. 24 s. In this case of cold start, the most common case, the initial voltage across the tube is as high as 8l0 kV until the cathode emission A circulator protects the tube from microwave power reflected by the accelerating structure. Auxiliary systems provide a high vacuum inside the accelerator, and cooling and temperature control of its conducting surfaces. The klystron and gun are powered by a high voltage modulator, which converts ac power from the electrical mains into a repetitive stream of pulses that are stepped to high voltage using a pulse transformer. The microwave tube is usually mounted directly into the Components of a microwave.oven The components that make up a microwave oven are: □ a highvoltage transformer, which passes energy to the magnetron, □ a cavity magnetron, □ a magnetron control circuit (a microprocessor), □ a waveguide, and □ a cooking chamber. Transformer A transformer, as shown in the photograph below, is a component that transfers electrical energy from one circuit to another through electromagnetic induction (refer to page 39 for transformers and It consisted of a Morse code key and a battery connected to the primary of a high voltage transformer, whose secondary coil was connected to the spark gap, tank circuit, and antenna. When the key was closed, a high voltage appeared at the secondary of the transformer that would charge.the capacitor. After reaching a certain voltage, a spark would jump between the electrodes causing damped oscillations in the tuned circuit. The high peak voltage reaching the antenna caused Current distribution in barretter; Microwave power; Barretter; Bolometer; 11528.

In domestic microwave ovens the anode voltage affects the microwave output power strongly. Almost all the domestic microwave ovens use ferroresonant constant voltage transformer, which holds Pulsed RF power Input voltage and impedance source Power rise time Power flattop time Power fall time FIGURE 2.9 Linking parameters for connecting pulsed power to the microwave. from prime power, the output of pulsed power components can be characterized by three classes of possible downstream elements: (1) another pulsed power component for further pulse.compression, (2) directly to a microwave source, or (3) an impedance and voltage transformer. In the last case, the
