ELECTROSTATIC PROTECTION CIRCUIT, INTEGRATED CIRCUIT CHIP, AND HOUSEHOLD APPLIANCE

Номер: WO2019119980A1
Автор: LIU, Dongzi, FENG, Yuxiang
Принадлежит:

An electrostatic protection circuit, an integrated circuit chip, and a household appliance. The electrostatic protection circuit comprises a circuit unit to be protected (100), an input electrostatic protection unit (200), and an output electrostatic protection unit (300). The input electrostatic protection unit (200) is connected between an input terminal (VIN) of the circuit unit to be protected (100) and a preceding circuit stage. The output electrostatic protection unit (300) is connected between an output terminal (VOUT) of the circuit unit to be protected (100) and a following circuit stage. The invention adds the input electrostatic protection unit (200) at the input terminal (VIN) of the circuit unit to be protected (100) and adds the output electrostatic protection unit (300) at the output terminal (VOUT) of the circuit unit to be protected (100), so as to effectively resist the impact of a surge from the preceding or following circuit stage on the circuit unit to be protected.

HIGHLY INTEGRATED INTELLIGENT POWER MODULE AND ELECTRICAL DEVICE

Номер: WO2019237637A1
Автор: LIU, Dongzi, FENG, Yuxiang
Принадлежит:

A highly integrated intelligent power module and an electrical device. The highly integrated intelligent power module comprises: a rectifier bridge (20) for connecting to an alternating-current power source and rectifying the alternating-current power source into a direct-current power source; a control module (10) for outputting a first control signal and a second control signal; a power switch module (30) for operating according to the first control signal, so that a PFC circuit composed thereof performs power factor correction on the direct-current power source; a plurality of power modules (40) for driving corresponding loads for operation according to the second control signal and the power factor corrected direct-current power source; and a mounting substrate (100), the control module (10), the rectifier bridge (20), the power switch module (30) and the plurality of power modules (40) being integrated on the mounting substrate (100). The invention solves the problem that when an electrical ...

CIRCUIT WITH ELECTROSTATIC PROTECTION FUNCTION, HIGH-VOLTAGE INTEGRATED CIRCUIT, AND AIR CONDITIONER

Номер: WO2019148910A1
Автор: LIU, Dongzi, FENG, Yuxiang
Принадлежит:

A circuit with an electrostatic protection function, a high-voltage integrated circuit, and an air conditioner. The circuit with the electrostatic protection function comprises a voltage detection circuit (10), a main bleeder circuit (20), and a circuit to be protected (30). The voltage detection circuit (10) is used for detecting an electrostatic voltage between a power supply line (VDD) and a grounding line (VSS). The main bleeder circuit (20) is configured to provide a main bleeding channel for a static current. The circuit to be protected (30) comprises a main circuit unit to be protected (31) and an auxiliary protection circuit (32). The auxiliary protection circuit (32) can carry out secondary bleed-off on electrostatic energy which is not completely bled off from the main bleeder circuit (20), and simultaneously can bleed off the electrostatic energy entered from a signal input end of the main circuit unit to be protected (31) so as to prevent static electricity from entering the ...
