Abstract
The utility model relates to the field of double-tube isolation transformers, in particular to a drive circuit of a transformer, which comprises a high-voltage input module, a rectifying and filtering module, a drive control module, a push-pull drive module, a switch drive module, a drive power supply module and a low-voltage output module. The power input end of the high-voltage input module is connected with commercial power, the control end of the drive control module is electrically connected with the input end of the push-pull drive module, and the output end of the push-pull drive module is electrically connected with the input end of the switch drive module. The output end of the switch driving module is electrically connected with the input end of the low-voltage output module, the output end of the low-voltage output module outputs low-voltage power to an electric appliance, and commercial power is output to the low-voltage output module after passing through the high-voltage input module and the rectifying and filtering module; the driving control module and the switch driving module control the opening and closing of the low-voltage output module; the push-pull driving module reduces the turn-on loss, and the driving efficiency is high.
