Fig. 2 is the utility model discloses structural schematic behind photovoltaic energy storage charging shed adjustment ceiling gradient. As shown in fig. 2, the utility model discloses photovoltaic energy storage charging shed can adjust the inclination of ceiling 1 through drive adjusting device to can promote the efficiency of absorption light energy. The driving adjusting device can comprise a driving motor and an executing device connected with an output shaft of the driving motor, the executing device is connected with the lower end of the ceiling 1, and the driving device and the executing device drive the inclination angle of the ceiling 1. It should be noted that the present invention does not limit the specific form of the driving adjustment device, and the person skilled in the art can select the corresponding device according to the requirement as long as the inclination angle of the ceiling 1 is adjusted.

The chopper circuit module controls the chopper circuit module through the control chip to achieve maximum power tracking. The photovoltaic panel is used for providing power for each module. The IR2101 inverter circuit module mainly realizes the conversion of DC/AC, and is provided with the electric energy of the maximum power point by the chopper circuit.

Fig. 3 is the utility model discloses inverter circuit's schematic diagram in photovoltaic energy storage charging shed. As shown in fig. 3, H1 and H2 are IR2101 integrated driving chips, VQ1, VQ2, VQ3 and VQ4 are MOS transistors, and Up, Un, Vp and Vn are two-phase four-path PWM waves output from the SPMC75F2413A single chip microcomputer. The upper and lower arms of one phase of PWM wave are Up and Un, the upper and lower arms of the other phase of PWM wave are Vp and Vn, and the PWM wave output from the single chip microcomputer can not drive a high-power MOS tube, so that the bootstrap capacitors C1 and C2 are charged by diodes VD1 and VD2 (adopting the quick recovery function of a Schottky tube to boost the capacitor charging voltage and reduce the energy consumption in the turn-off process) by utilizing the capacitor bootstrap function of the IR2101, so as to boost the signal voltage of the drive MOS tube, so that the signal voltage has the function of expanding the signal output, the expanded signal PWM wave can orderly control the on-off of VQ-1, VQ2, VQ3 and VQ4, and the drive signals of the upper and lower arms of the same phase in an inverter circuit are complementary.

When the Up input is high, the HO output is also high, and the VQ1 can be controlled to be on by the capacitive bootstrap function of the IR2101, at this time, because the LO output is low, the VQ2 cannot be driven, so the VQ2 is in an off state, and at the same time, Vp also inputs a high level, that is, HO is high, so the VQ4 is in an on state, and at this time, the VQ3 is in an off state, so T1 → VQ1 → R5 (load) → VQ4 → GND forms a path. Conversely, when Up and Vp are at a low level and Un and Vn are at a high level, i.e., the main flow direction of the current is T1 → VQ3 → R5 (load) → VQ2 → GND, the 4 MOS transistor switching devices are alternately turned on and off in order, and an alternating current is formed at R5 (load). In practical application, in order to prevent short circuit caused by simultaneous conduction of the upper arm and the lower arm, dead time is added in the process of software design to protect the whole circuit.

Fig. 4 is the utility model discloses chopper circuit's in photovoltaic energy storage charging shed schematic diagram. As shown in fig. 4, the circuit is mainly used for maximum power tracking, a power supply of the circuit is an independent voltage source, R6(30 Ω/30W) is a power resistor which mainly serves as a power supply internal resistance, R7 and R8 are voltage dividing circuits formed for detecting a voltage value of a load end, detection is performed through Ud1, a detection result is returned to a single chip microcomputer for processing, and the on-off time of VQ5 is controlled by adjusting the duty ratio of a PWM wave. When the Ud1X (R7+ R8)/R8 value is detected to be larger than half, the single chip microcomputer can adjust the duty ratio of the chopper circuit to be larger, the voltage passing through the chopper circuit is increased, the value of the chopper circuit is further close to half of that of the photovoltaic cell, and if the value of the chopper circuit is detected to be smaller than half, the duty ratio is adjusted to be smaller, the voltage passing through the chopper circuit is reduced, and therefore the frequency tracking function is achieved through tracking voltage.
