Digital Sensor less Current Mode Control Based on Charge Balance Principle and Dual Current Error Compensation for DC-DC Converters in DCM
Abstract
For Discontinuous Conduction Mode (DCM) dc– dc converters with digital sensor less current mode (DSCM) control, a watched current mistake happens, inferable from a low-exactness current eyewitness. In addition, a reference current mistake happens because of a low-precision current controller or a finite dc increase of current circle. Ordinarily, the watched current is repaid to expand current guideline exactness, though the reference current mistake is dismissed. Notwithstanding, for charge balance principle (CBP)- based DSCM (CBP-DSCM) control, this paper demonstrates that the reference current ought to be remunerated in an equivalent amount to that of watched current. Something else, single or unequal pay prompts yield voltage consistent state mistake.
