摘要： A non-directional frequency generator spark prevention apparatus including a plurality of electric connections connected with a direct current power source, i.e., brushes, and a commutator for converting direct current waveform inputted through the brushes into alternating current waveform by rotational movement thereof, and for outputting the alternating current waveform. A voltage pulse controlling part is connected between the brushes of the non-directional frequency generator, while having a resistor and a transistor which are connected in series with each other, and the transistor is operated synchronously with the rotation of the commutator of the non-directional frequency generator. By controlling the electric current to flow through the transistor during the brush-off period, a spark production during the brush-off period can be prevented. Further, by controlling the transistor to be turned off during a predetermined period between a predetermined time of the brush-off period to a predetermined time of the brush-on period, the electric current does not flow through the transistor at the beginning of the brush-on period, and accordingly, the spark production at the beginning of the brush-on period is prevented. A corresponding pulse generating part includes a photo-interrupter and a photo sensor, for generating a predetermined pulse waveform corresponding to the rotation of the commutator. Based on the pulse waveform, the transistor is operated, and accordingly, the transistor precisely synchronizes with the rotation of the commutator of the non-directional frequency generator.

摘要： A non-directional frequency generator inputs direct current power and outputs alternating current power. A high voltage transformer inputs the alternating current power, and either induces a higher voltage for driving the magnetron, or induces and outputs a commonly used alternating current power. A button inputting section includes a microwave oven operating button for driving the magnetron, and a voltage supplying button for supplying the commonly used alternating current power. A microcomputer applies the higher voltage of the high voltage transformer to the magnetron when there is a button input through the microwave oven operating button, while outputting the commonly used alternating current power when there is a button input through the voltage supplying button. Further, a socket outlet is formed on the body of the microwave oven, through which the commonly used alternating power generated at the microwave oven is supplied. Accordingly, since the commonly used alternating current power is supplied from an AC/DC type microwave oven, a user can use AC type electric appliances in places where alternating current is unavailable.

摘要： An AC/DC type microwave oven has a function of managing an input power source. The AC/DC type microwave oven comprises a rotatable inverter which inverts a DC power source to an AC power source by a rotational force, a high voltage transformer which receives a common power source or an AC power inverted by the rotatable inverter and outputs a higher voltage, a magnetron which is driven by the high voltage outputted from the high voltage transformer and radiates a microwave and a power control unit for sensing a signal from a power selecting key and preventing the AC and DC power sources from being simultaneously inputted. Therefore, both of AC power and DC power are prevented from being simultaneously supplied to the microwave oven which could result in a malfunction, or an overload occurs in the electric components of the microwave oven. Therefore, only one input power of the common and DC power sources is selected and, the microwave oven is operated properly. The remaining voltage of the battery is always detected and displayed through the display, thereby preventing a complete discharge of the battery.
