Abstract

uma fonte de alimentação de modo de comutação não-isolado para faixa de luz de alta tensão é revelada. a fonte de alimentação de modo de comutação não-isolado compreende um circuito retificador de ponte inteira, um tubo de comutação q2, um capacitor eletrolítico c2, um indutor de armazenamento de energia l1, um diodo d4 e um circuito pwm. uma extremidade de saída de sinal pwm do circuito pwm é conectada a um eletrodo de controle do tubo de comutação q2, o tubo de comutação q2 e o diodo d4 estão em conexão em série entre as duas extremidades de saída do circuito retificador de ponte inteira, um eletrodo negativo do tubo de comutação d4 é conectado a uma extremidade de saída positiva +vcc do circuito retificador de ponte inteira e o indutor de armazenamento de energia l1 é conectado entre um eletrodo negativo do capacitor eletrolítico c2 e um eletrodo positivo do diodo d4. a fonte de alimentação do modo de comutação não-isolado usa uma estrutura de circuito nova; a tensão do indutor de armazenamento de energia l1 é mantida em 130v em virtude da modulação de largura de pulso do circuito pwm, de modo que o capacitor eletrolítico c2 pode sempre produzir uma alta tensão de 180v e o custo da fonte de alimentação é baixo. portanto, as empresas de fabricação de faixa de luz de alta tensão podem ser mais competitivas do que outras.
