摘要: The continuous conduction mode (CCM) boost voltage power factor correction apparatus with an average-current control mode of the present invention uses resettable integrators to integrate the difference voltage signal outputted from the voltage error amplifier and the input current signal obtained from detection. The integration results are then compared to control the duty cycle of the switch. Thereby, the input current and the input voltage in the AC/DC electrical power converter have a proportion relation and their phases are the same as each other. The components used in this control method are simpler than the PFC circuit of the prior art. It is easy to integrate in one chip with fewer pins. The apparatus of the present invention has a high power factor and a low total harmonic distortion (THD).

摘要: A high-speed, solid-state circuit breaker is capable of interrupting high DC currents without generating an arc, and it is maintenance-free. Both the switch and the tripping unit are solid-state, which meet precise protection requirements. The high-speed, solid-state DC circuit breaker uses an emitter turn-off (ETO) thyristor as the switch. The ETO thyristor has an anode, a cathode and first, second and third gate electrodes. The anode is connectable to a source of DC current, and the cathode is connectable to a load. A solid-state trip circuit is connected to the first, second and third gate electrodes for controlling interrpution of DC current to the load by turning off said ETO thyristor.

摘要: A trench process for establishing a contact for a semiconductor device with trenches such as the trench and planar MOSFETs (UMOS), trench and planar IGBTs and trench MCTs which reduces the number of masks and eliminates the need for lateral diffusion into the trench channel region. Improved control of the parasitic transistor in the trench MOSFET is also achieved. The cell size/pitch is reduced relative to conventional processes which require source block and P+ masks.

摘要: A trench emitter controlled thyristor 30 having a collector layer 32, a drift layer 34, a body layer 36, and a floating layer 38. Each of the layers 32, 34, 36, and 38 contacts the adjacent layer(s). The floating layer 38 does not cover the entirety of the adjacent layer (the body layer 36) but at one of the lateral ends of the thyristor 30, an emitter 40 is formed. A gate area (or electrode) 43 is formed to span laterally across the thyristor 30. Additionally, trenches are formed into the lateral edges 44 of the body layer 36 and a portion of the drift layer 34. Within the trenches 44 are formed additional gate area 42 which runs for substantially the length of the thyristor 30. The gate 42 is kept electrically isolated from the remainder of the thyristor by an insulating region 46 directly over the body layer 36.
