Patent

FSP Group has been researching and developing power supply for more that 20 years, whose patents range from the whole power supply industry, including PC power, IPC power, redundant power, adapter power, LED lighting power, TV power, UPS, PV inverter and Medical power.

This technology is applied to the PC power supply. The power supply via a conduction path formed by an inrush suppression component at an initial operation, so as to suppress the inrush current upon booting, and switch the conduction path to another conduction path having low impedance to reduce power consumption after the input power becomes stable.

This technology is applied to the inverter of the photovoltaic system. The inverter by determining whether the power variation between the disturbed input power and the undisturbed input power is greater than the predetermined variation, an error of the MPPT operation occurred due to shift of the input power caused by sampling a system noise is avoided, so as to improve operation stability of the whole inverter.

This technology is applied to the inverter of the photovoltaic system. The inverter using the voltage regulator-based ground detection circuit, and thereby generate one ground indication voltage indicating the voltage difference of the photovoltaic ground terminal of the photovoltaic module and the output terminal of the voltage regulator.  The inverter can determine whether a ground fault occurs to the photovoltaic module according to whether the ground indication voltage is located within the normal voltage range, and accordingly enable a corresponding protection mechanism.

This technology is applied to the power adapter. Using the front-end input rectifier filter circuit is independently disposed on the auxiliary circuit board, the main circuit board has more space for configuring circuit wirings and components. Therefore, under a condition of same electrical parameters and dimensions, the volume of the power adapter  is only a half of that of the existing power adapter, which satisfies a demand for miniaturization of the electronic devices.

This technology is applied to the redundant power supply. The slave power converter may be instructed to operate in the no-load conversion state and may not enter the sleep mode. If the master power converter can no longer supply power in a normal manner, the slave power converter enhances the voltage level of the auxiliary power onto the working voltage level, such that the main power can be replaced by the auxiliary power. The power supply to the load  is not terminated by the overly long time of awakening the slave power converter. 

This technology is applied to the elongated type power supply. The power supply fixing structure includes a connecting component and an interconnect structure formed at an outer casing of the elongated type power supply. Without changing the original power connection structure on the casing, the  elongated type power supply is reliably connected to the casing.

This technology is applied to the adapter power. With an input port configured at the converter in the additional function device, detachable assembly and connection to a power core unit can be achieved, and a plurality of power core units can be further assembled and connected to achieve a composite or redundant power output. External power supply module provides diversified matching capabilities, enablingthe external power supply module to be effectively utilized and reducing resource waste.

This technology is applied to the Burn-in test system. After the testing operation is performed on the power supply device, the testing power generated by performing the testing operation may be reused for driving the virtual currency calculating circuit to perform the virtual currency calculating operation. The testing power may be applied to perform a real-time virtual currency calculation, so as to gain additional revenue.  

This technology is applied to the elongated type ATX power supply and the elongated type FLEX power supply. The power supply fixing structure includes a connecting component and an interconnect structure formed at an outer casing of the elongated type power supply. Without changing the original power connection structure on the casing, the elongated type power supply is reliably connected to the casing.
