Supply circuit for equipment frequently on standby, comprises autofeeding circuit and voltage doubling starting circuit to start integrated circuit which controls interruptor in transformer primary |
摘要 |
The supply circuit consists of an alternating current supply (100) and rectifier(101) which feed a primary winding (103) connected to a switch (105) operated by an integrated circuit (109,110). A voltage doubling starting circuit (118) stores energy in a capacitance (300) during an initial start and supplies it to the integrated circuit subsequently using switches (303,404). After start operation is supplied by an autofeed circuit (107)
