Referring to FIG. 4, the charging and discharging flowchart of the power supply device of the present invention mainly includes several steps of rectification, filtering, voltage regulation, control, and feedback circuit. Figure 5 is a circuit schematic diagram of the device of the present invention. The unstable power is rectified to a relatively stable DC, and then controlled by the square wave width or frequency control to be AC, through the transformer output, and the output side is boosted through the boost circuit. Give the load. There are various specific implementation circuits, and the present invention will be further described below in conjunction with the specific drawings and one of the implementation circuits.

As shown in FIG. 5, in order to conveniently charge the load that needs to be charged, the present invention uses three charging methods to output electric energy. The left side of the circuit controls the primary side voltage of the transformer by controlling the state of the switching tube. The middle is the voltage stabilizing unit, and the output voltage is adjusted within the range. The right side is the secondary side of the transformer to charge the battery and the LED circuit responsible for indicating the voltage state.

The rectifier circuit, the hand-cranked generator generates unstable electric energy after the work is done, and the solar panel receives the light, and must be rectified to become a voltage-stabilized direct current. A three-phase uncontrolled rectifier bridge circuit consisting of six diodes is used to rectify the input power into a voltage stabilized direct current. Considering DC side overvoltage protection, before entering the three-phase rectifier bridge Add three sets of fuses on the road. Considering that the three-phase uncontrolled rectifier bridge is a whole module, the AC side has three wiring ports, and the other module external power supply of the present invention, that is, the single-phase AC power supply module, is connected to two of the three-phase uncontrolled rectifier bridges. Rectification is possible.

The filter circuit converts the electric energy into single-phase direct current after rectification. Considering that the charging power of the charging is small, the capacitor C1 is used for filtering in the circuit.

The voltage regulating circuit and the voltage regulating circuit adopt a single-ended flyback converter to achieve voltage stabilization during the voltage regulation process. The core of the high frequency transformer operates only on one side of the hysteresis loop (ie, the first quadrant). The function of the different name is to realize the magnetic reset of the internal coil of the transformer after the end of one cycle. The specific process of the circuit diagram of this module is: when the high voltage switch Q1 is excited by the square wave pulse, the input voltage is applied to the high frequency transformer. On the primary winding Np, since the rectifier diode D2 of the transformer T is reversely connected, no current flows through the secondary winding Ns: when the switching transistor Q1 is turned off, the polarity of the voltage on the secondary winding Ns is reversed, and the rectifier diode D1 is forward biased. The energy stored in the transformer during the conduction of the switch tube is released to the battery through the rectifier diode D2. The converter stores only energy during the conduction of the high-voltage switch tube, and transfers power to the battery during the cut-off period. The high-frequency transformer is both a transformer and an energy storage inductor during operation. The output end is a low-pass filter consisting of an inductor L1 and two C3 capacitors. The primary side of the transformer is provided with an RCD leakage inductance spike absorbing circuit composed of R2, C2 and D1.

Control and feedback circuits, in order to solve the problem of current instability, this circuit diagram adds a square wave pulse width or frequency regulator. In addition, on the basis of the basic circuit diagram, the function of the indicator light is added, and two light-emitting diodes D3 and D4 are arranged in the circuit. D3 is the charging indicator, D4 is the charging full indicator, the two lights are set to different colors to distinguish, the specific circuit process is: when charging the battery, D3 is in the on state, the illumination indication is charging. The reference voltage at the inverting input of operational amplifier U can be adjusted through resistor R7 and fed back via R5. By comparing with the voltage to the input terminal, if the voltage of the non-inverting input terminal of the arithmetic discharger U is greater than the voltage of the inverting input terminal thereof, the operational amplifier U outputs a high level, and at this time, the light-emitting diode D4 will be lit, indicating that the battery is fully charged; If the voltage of the non-inverting input terminal of the arithmetic discharger U is lower than the voltage of its inverting input terminal, the operational amplifier U outputs a low level, and at this time, the light-emitting diode D4 is not lit.
