Description
technical field [0001] The invention relates to the field of chargers, in particular to a charging control circuit of a storage battery charger. Background technique [0002] The charging control circuit of the current battery charger generally includes a three-phase synchronous transformer and three pulse transformers, resulting in many components and complex internal wiring, which increases the cost. The phase shift range of this charging control circuit can reach 180 degrees, but for the back EMF load of the charger, due to the existence of the back EMF, the actual required phase shift range is only 120 degrees. Contents of the invention [0003] The object of the present invention is to provide a charging control circuit of a storage battery charger to solve the above-mentioned problems. [0004] The technical problem solved by the present invention can adopt following technical scheme to realize: [0005] A charging control circuit of a storage battery charger, char...
