Abstract

MPLIFICADOR COMUTÁVEL. A fim de obter um amplificador de voltagem e amplificador de corrente leve e robusto para um aparelho de teste (10) para testar um componente elétrico, um amplificador (8) está configurado para emitir um sinal de teste em uma saída de sinal, entre uma ligação de saída positiva (P) e uma ligação de saída negativa (N), sendo que o amplificador compreende uma primeira meia-ponte (HB1) e uma segunda meia-ponte (HB2), sendo que está prevista uma unidade de comutação (7), que está configurada para ligar, em um primeiro modo de operação (Mi), a primeira meia-ponte (HB1) e a segunda meia-ponte (HB2) paralelamente sobre a saída de sinal e ligar, em um segundo modo de operação (Mu), a primeira meia-ponte (HB1) e a segunda meia-ponte (HB2) em série sobre a saída de sinal.
