摘要 励磁电源是保证速调电视发射机正常工作的核心部件,又称聚焦电源,因其要求精度高,所以励磁电源采用电源型电源。励磁电源由分流电路、调整电路、保护电路组成对其常见故障进行分析,提出解决办法。 The field current source, also called the focusing source, is the core which guarantees the regular operation of the klystron TV transmitter. It requires high precision and therefore adopts the current source. The field current source, which has a high fault rate, consists of three parts: the diffluence circuit, the adjusting circuit and the protecting circuit. This article attempts to deal with the faults of the circuit and present a theoretical analysis.
