摘要： An light emitting diode (LED) control, a plurality of duty cycle signals corresponding to a plurality of LEDs are stored in a dual-port memory by memory mapping. By sampling, the stored duty cycle signals are outputted to generate a plurality of parallel single-bit data each having one single bit. After the single-bit data are converted by a data transmission module, each bit of the single-bit data is serially outputted to a drive module to drive the LEDs. Thus, the ON duty cycles of the LEDs are modulated by pulse width modulation (PWM), light emitted from the LEDs are mixed in time-domain, and the brightness of the LEDs can be controlled.

摘要： A two-stage isolated DC/AC conversion circuit structure, consisting of a main switch, a second switch attached to a controller, another controller for controlling, and in work mode 1 and 2, after passing through the capacitor filter the low frequency half sine wave power is stored on this capacitor. After an inductor outputs the low frequency half sine wave power through this capacitor filter, it can respectively pass through the first and second transformers to increase the voltage, and then pass through the first and second secondary diode rectifiers, outputting the positive and negative half waves AC to the end user, and allow the end user to obtain the whole wave of the AC. Using the first and second diodes prevents outputting in reverse, and has the effect of isolation, and prevents all the stored energy for the later stage end user recharging to the front stage DC/AC conversion circuit.
