'knock down' is not the right term
PWM means Pulse Width Modulation
the power is pulse on and off hundreds of time a second to maintain a set point voltage aka 14.?
the higher the battery voltage (state of charge) the shorter the on time of the pulse and the longer the OFF time between pulses
thats the simple basic straight forward explanation of the operation
