Abstract
"CIRCUITO DE SUPRIMENTO DE ENERGIA DE COMUTAçãO". Um circuito de suprimento de energia de comutação que é pequeno, de peso leve, e altamente eficiente em conversão de potência, inclui um transformador de conversor de isolamento, que é formado por um núcleo sem abertura e um enrolamento primário e secundário enrolados no núcleo tal que a indutância mútua entre os enrolamentos exibe um modo aditivo. Um circuito de retificador de meia onda é provido no lado secundário do circuito e executa uma operação de retificação no modo aditivo para obter uma tensão de saída de CC lateral secundário. Em um sistema de circuito de controle de tensão constante para estabilizar a tensão de saída lateral secundário, a freq³ência de comutação de um elemento de comutação é variado em resposta ao nível de tensão de saída lateral secundário para controlar a impedância de ressonância de um circuito de ressonância paralelo lateral primário e o ângulo de continuidade do elemento de comutação de forma composta."SWITCHING ENERGY SUPPLY CIRCUIT". A switching power supply circuit that is small, light weight, and highly efficient in power conversion, includes an isolation converter transformer, which is formed by an unopened core and a primary and secondary winding wrapped around the core. that the mutual inductance between the windings exhibits an additive mode. A half-wave rectifier circuit is provided on the secondary side of the circuit and performs a rectifying operation in the additive mode to obtain a secondary lateral DC output voltage. In a constant voltage control circuit system to stabilize the secondary side output voltage, the switching frequency of a switching element is varied in response to the secondary side output voltage level to control the resonance impedance of a circuit. primary lateral parallel resonance and the continuity angle of the composite switching element.
