Abstract This paper describes a new self-resonating switch-mode power supply for driving CW magnetrons, based on the Boucherot effect. A detailed circuit analysis is given and its performance is evaluated for an 800W/2450MHz magnetron, whilst work at high power driving a magnetron up to 40kW is reported. A comparison of the supply with the conventional power-supply used in microwave ovens is made and the principal features of the new design are found to be: low energy dissipation under short-circuit conditions, low ripple current and voltage waveforms that result in more precise control in the range 20-100% of rated power, high efficiencies and small size and weight. Key Words: : Boucherot, switch mode, power supply, microwave heating, magnetron
