3, the full set of mobile power supply design based on ARM-CORTEX M3 ~!
This circuit is primarily a human computer interactive product designed around the monitoring and operation of mobile power. This circuit uses STM32F103 (STM32F103 data manual) as a main control chip; a partial circuit boost is implemented using the chip TP 4056, and the voltage regulator output 3V and 5V is achieved by HT7527A, providing a power supply to the single-chip STM32F103 and PWM circuitry. Using the chip DW01 to realize the protection circuit module, realize overcharge, overlapping, overcurrent, and short-circuit protection. When the charging voltage is low, the output PWM is activated; when the charging voltage is high, the output PWM is turned off. The BTL006 liquid crystal display is implemented using the LCD drive chip HT1621B (HT1621B data manual) and the single-chip STM32F103, and the current mobile supply voltage and current can be seen by BTL006. It has achieved a good circuit protection; support USB interface charging.

7, POWERON - integrated mobile AC power supply
There are a large number of battery packs on the market, but for any people looking for mobile power sockets, the choice is limited. We can find a large number of 120V ACs, but are subject to price, portability and performance combination. Now this is the reason why our project Poweron is produced! Using the box, it can convert 17 to 30 V DC to 120V AC, and can automatically switch to the socket. The user can control the box by a magnetic knob or an online instrument panel.
Most importantly, with the company's Coolmos super knot transistor, the project provides smooth sinusoidal waveforms. The smoothed current waveform created is suitable for a variety of household devices. In particular, inductive load and TRIAC-based dimmer are particularly sensitive, fluorescent lamp ballasts are ringing, motor temperature rise, and the dimmer shows the act of unexpected. Therefore, a very similar waveform that is very similar to the common power supply will be more compatible with various electrical appliances.
