摘要： It is an object of the present invention to provide an inverter circuit including a power arm ensuring a high breakdown voltage and having low probability of malfunction. In a power arm element consisting of a switching element and a diode connected in inverse-parallel connection thereto, n free wheeling diodes (n≧2) connected in series are connected in inverse-parallel connection to a switching element (1b). A breakdown voltage between an anode and a cathode of each free wheeling diode is defined to be 1/n of a breakdown voltage of the switching element (1b). That is, the breakdown voltage of each free wheeling diode is reduced to 1/n to reduce a thickness of a n− drift region. A transient voltage characteristic during flow of a free wheeling current can be thereby kept low. The drop in the breakdown voltage is compensated with the n free wheeling diodes connected in series, to thereby ensure breakdown voltage of a degree approximately the same as that of the switching element.

摘要： An inverter apparatus includes an inverter circuit for driving a load. This inverter circuit has at least a pair of switching elements connected in series in a forward direction between both polarity terminals of a dc supply for supplying power to a load. An inverter drive circuit is employed for driving each switching element of the inverter circuit and has at least one high withstand voltage IC wherein the signal level reference potential is different in the input signal and the output signal. A clamping circuit clamps the potential of the low voltage side reference terminal, to which a potential, that is a reference for operation of the high withstand voltage IC in the inverter drive circuit and is a reference for a signal on the low potential side of the high withstand voltage IC, is applied. The voltage is clamped to the high voltage reference terminal to which is applied a reference potential for the high potential-side signal in the high withstand voltage IC. The inverter apparatus also includes a voltage dividing circuit for voltage dividing a voltage between the low voltage side reference terminal of the high withstand voltage IC in the inverter drive circuit and the negative electrode of the dc supply.

摘要： In a semiconductor substrate, semiconductor regions belonging to the IGBT are formed in an IGBT region and semiconductor regions belonging to the diode are formed in a diode region. The IGBT and the diode are connected in anti-parallel to each other. A trench in which an insulator is buried is formed between the IGBT region and the diode region. The insulator restricts the reverse recovery current which flows from the diode region into the IGBT region. Thus, semiconductor regions of an IGBT and a diode connected in anti-parallel with each other are fabricated in a single semiconductor substrate and the chip size is reduced.

摘要： Disclosed is a method of driving a power converter which can simplify a charging sequence of a charge pump capacitor to reduce the time required to design the device without using a voltage protective circuit and optimum design required to determine the capacitance of the charge pump capacitor. A charging pulse signal for a capacitor (CP) is provided as an input signal from an external control device (EC) substantially simultaneously as a control power source (PS) is switched on to provide a predetermined control power source voltage (V.sub.PS). A driver circuit (DR20) outputs a control signal (V.sub.D) to turn on a transistor (Q2) in a pulse-like manner, starting charging the capacitor (CP). The charging pulse signal continues being provided after completion of the charging of the capacitor (CP) and stops being provided immediately before a PWM signal is provided.

摘要： A controller for power devices which is not required to individually insulate high and low potential portions and to include an insulated power supply is disclosed. An external controller (6) is connected to a second internal control circuit (4) which is in turn connected to a level shift circuit (5) and a gate electrode of a transistor (Q2). Power supply voltage (V1) is applied to the second internal control circuit (4) for operation thereof. The level shift circuit (5) is connected to a first internal control circuit (3) which is in turn connected to a gate electrode of a transistor (Q1) and a charge pump circuit (7). Control of a first semiconductor circuit is made through the level shift means in response to an input signal generated on the basis of a second main power supply potential, thereby achieving increased responsiveness of the power devices to a control signal and improved integration.

摘要： When an IGBT element (9) is turned off and an IGBT element (19) is turned on, capacitors (1, 2) are charged by a current successively passing through the capacitor (1), a resistive element (4), a diode (5), the capacitor (2) and an intermediate wire (32) from a high-potential dc bus (30). At the same time, a capacitor (11) is discharged by a current successively passing through a diode (17), a resistive element (16) and the capacitor (11) from a low-potential dc bus (31) to flow to the intermediate wire (32). When the IGBT element (9) is turned on and the IGBT element (19) is turned off, on the other hand, the capacitors (11, 12) are charged and the capacitor (1) is discharged. The above is so repeated as to maintain source voltages of driving circuits (8, 18) at values exceeding constant levels. Thus, a power circuit for a driving circuit is formed by a simple circuit element.
