Abstract
''CONVERSOR DE RETORNO DE MODO CONTìNUO''. Em um conversor de retorno de modo contínuo um transistor FET (110) é provido para reduzir a queda de voltagem no lado secundário do transformador. O uso do transistor FET torna o conversor mais adequado para aplicações de baixa voltagem uma vez que menores perdas de corrente são impostas no lado secundário do conversor do que em um conversor convencional. O conversor possui também um capacitor de bloqueio de CC (117) para redução adicional das perdas de corrente no lado secundário.
