This discontinuous conduction mode (DCM) non-isolated 800-W SEPIC converter battery charger reference design provides an adjustable output voltage and current. The output voltage can be adjusted from 282 V to 400 V by setting an external DC voltage between 0 V to 3 V. The output charging current can be adjusted between 0 A to 2 A by adjusting the duty cycle of a PWM input. It operates over an input voltage range of 340 Vdc to 420 Vdc. Independent voltage and current feedback loops are used to maintain regulation.
