Abstract
Disclosed are an electromagnetic induction type magnetic energy collector based on capacitive energy storage and a power improvement method. A main energy acquisition coil is sleeved in a main circuit to collect magnetic field energy, and a detection coil is sleeved in the main circuit to generate a sinusoidal signal for detecting zero crossing of a primary current; a switch group S2 and a switch group S1 are alternately turned on and off, a first rectifier bridge is connected to the switch group S2 and the switch group S1, and a comparator circuit is connected to the detection coil to compare the sinusoidal signal and convert the sinusoidal signal into a zero-crossing square wave signal; and a control module is connected to the comparator circuit, determines the zero crossing of the primary current based on the zero-crossing square wave signal.
