The invention discloses an improved electronic transformer. The body of the improved electronic transformer is a circuit board, and a rectifying circuit, a starting circuit, an oscillation circuit and a low-voltage output circuit are mounted on the circuit board. An input end of the rectifying circuit is used for being connected with input voltage, an output end of the rectifying circuit is connected with the starting circuit, the other end of the starting circuit is connected with the oscillation circuit, and an output end of the oscillation circuit is connected with the low-voltage output circuit. The improved electronic transformer has the advantages that the improved electronic transformer is lighter in weight, smaller in size, lower in cost and more energy-saving than an iron core transformer, is simpler in structure, lower in cost, fewer in components and faults than a switch transformation power source, and is safe and reliable to use and wide in operation range of voltage, current and power, and a high-voltage end and a low-voltage end of the improved electronic transformer are completely isolated.
Description
technical field [0001] The invention relates to the field of transformers, in particular to an improved electronic transformer. Background technique [0002] The working principle of an electronic transformer is very similar to that of a switching regulated power supply, and it is actually an AC inverter. Firstly, the alternating current is converted into pulsating direct current, and then a high-frequency oscillator is composed of electronic components to convert the direct current into high-frequency alternating current, and then the required high-frequency alternating current is output through the electronic transformer, and then secondary, rectified and filtered to obtain low-voltage direct current. Its characteristic is that the electronic transformer does not use many electronic components in the circuit like the switching regulated power supply. [0003] It is a new type of electronic transformer developed on the basis of the circuit principle of high-frequency elect...
