The manufacturer of pwm solar charge controller tells you that PWM is pulse width modulation, which refers to the use of the digital output of the microprocessor to control the analog circuit, and is a method of digitally encoding the level of the analog signal. The pwm solar charge controller manufacturer tells you that digitally controlling the analog circuit can greatly reduce the cost and power consumption of the system.

The electrical structure of the pwm solar charge controller is relatively simple. It is mainly composed of a main power switch, a capacitor, a driver and a protection circuit. It is actually equivalent to a switch. When the component and the battery are connected together, the voltage of the component will be pulled down. to a voltage close to that of the battery pack.
The charging method of the pwm solar charge controller is to charge the battery with a pulse current that automatically changes the duty cycle, so the pulsating charging can make the battery more safely and quickly fully charged, and the oxygen generated by the chemical reaction of the battery has time to recharge during the disconnection period. Combined and absorbed, the concentration polarization and ohmic polarization are naturally eliminated, thereby reducing the internal pressure of the battery, so that the battery can absorb more electricity. The pulse charging method enables the battery to have a sufficient response time, reduces the gassing amount, and improves the acceptance rate of the battery to the charging current.
