Power reduction output circuit of power supply transformation device for high-voltage supercapacitor

摘要: The invention provides a power reduction output circuit of supply transformation device for high-voltage supercapacitor. comprises an input voltage detection unit, comparison hysteresis current loop PWM master control unit and unit. the receive direct voltage. transmits signal to through adoption isolation optocoupler switch mode. linear collects inputs in Compared with prior art, according supercapacitor, when is very low, limit can be controlled, element at low-voltage side effectively protected, security reliability are improved.
