Abstract

A transformerless charging system including a charging circuit including a first switch and a second switch, a first sensor assembly configured to measure a voltage of the battery, a second sensor assembly configured to measure a voltage of an input power line, and a third sensor assembly configured to measure a current of the charging circuit. An electronic processor is configured to receive a voltage of the battery, receive a voltage of the input power line, compare the voltage of the battery to the voltage of the input power line, and in response to the voltage of the input power line being greater than or approaching the voltage of the battery, turn off a PWM signal to the first switch, and with the PWM signal off, receive a current of the charging circuit and, in response to the current of the charging circuit being 0 Amps, open the second switch.
