A reverse current occurs when there is a higher voltage at the output of a system than the input, causing the current to flow back through the system. The positive voltage will draw the electrons to the battery and will reject the holes, causing the current to flow into the circuit.
The various methods for the control of output voltage of inverters can be enumerated as follows: External control of the AC output voltage. External control of the DC input voltage. Internal control of the inverter output voltage (PWM control). PWM method is referred to as the internal control method.
If the solar power input is reversed, the power will form a short circuit through the anti-parallel diode. According to the characteristics of the solar module, the voltage of the solar power supply When pulled down, the voltage value is only the sum of the forward voltage drop of the two diodes, which will not damage the electrolytic capacitor.
In the context of the photoelectric effect, a reverse voltage is a voltage that opposes the flow of electrons. This is also known as a "stopping" or "retarding" potential. The work function of the material plus the stopping potential multiplied by the charge on the electron would equal the energy of the original photon.
When AC inverters are used to feed AC loads, it is necessary that they provide provision for voltage variations so as to supply the required voltage to AC loads. The voltage required by AC loads may be constant or adjustable.
For example, solar controllers such as grid-connected inverters, off-grid inverters and pumping inverters will connect electrolytic capacitors in parallel on the DC input side to support the DC voltage.
