Modular microwave power supply

Abstract

The invention relates to a microwave power supply and particularly relates to a modular microwave power supply. The power supply comprises an input power supply, a first alternating current transformer, a first rectifying module, a filtering module, an inverter, a second alternating current transformer and a second rectifying module, wherein the input power supply is connected with the first alternating current transformer for voltage regulation, the first alternating current transformer is connected with the first rectifying module for converting alternating current into direct current, the first rectifying module is connected with the filtering module for filtering, the filtering module is connected with the inverter used for converting the filtered direct current into the alternating current, the inverter is connected with the second alternating current transformer for voltage regulation, the second alternating current transformer is connected with the second rectifying module usedfor converting the alternating current into the direct current, and the second rectifying module outputs the direct current to a magnetron. The power supply is advantaged in that the power supply caneffectively overcome defects that in the prior art, the output power cannot be effectively calibrated, more electronic elements are needed, and the generated harmonic waves seriously pollute the powergrid.

Description

technical field [0001] The invention relates to a microwave power supply, in particular to a modularized microwave power supply. Background technique [0002] Microwave refers to electromagnetic waves with a frequency of 300MHz-3000GHz and a wavelength of 0.1mm-1m.
