[Shan Wei Technology Co., years of industry experience, to provide you with professional service! ! ! ] Maintenance procedures and experiences of four industrial power, industrial power supply repair theory, there are many industrial power using UC38 ×× series 8-pin PWM components, most of the power is not working due to a power inverter startup resistor damage repair price, or chip Performance landing. When no VC after breaking R, PWM module does not work, the need to change the original power of resistance of the same resistance. When the PWM module startup current increases, the value of R can be reduced to the PWM module can work so far. GE DR in the repair of a power inverter repair factory, PWM module for UC3843, found no other abnormalities detected in R (220K) and resistors on a 220K drive after the maintenance of quality, PWM module, the output voltage is normal. There are hours of illnesses due to the external circuit, resulting in VR terminal voltage is 0V 5V drive repair tips, PWM module does not work Siemens inverter repair, repair Kodak in 8900 when the camera power inverter repair encounter this situation, the end is connected to the VR The external circuit is disconnected, VR goes from 0V 5V, PWM module is working properly, the output voltage is normal.
