METHOD AND REGULATED SWITCH-MODE SECONDARY POWER SUPPLY FOR DC VOLTAGE INVERSION

摘要

FIELD: electrical engineering; switch-mode secondary power supplies. SUBSTANCE: feedback signal is additionally regulated depending on on-off time ratio of pulses applied to primary winding of transformer. Proposed regulation enables compensation for output voltage variation of inverter as function of load current variation. Proposed method is implemented by introducing controlled voltage divider in prior-art power supply. EFFECT: enhanced output voltage stability. 2 cl, 1 dwg
