摘要： An inverter power supply operating at a high efficiency to provide an AC voltage to a load. The power source includes a DC voltage source and an output transformer with a primary winding, secondary winding, and a feedback winding. An FET is connected in series with the primary winding across the DC voltage source. The primary winding is connected to a capacitor to form a L-C resonant circuit which, in response to the switching of FET, provides across the primary winding an oscillation voltage to be applied through the secondary winding to drive a load, while inducing a feedback voltage across the feedback winding. The oscillation voltage is allowed to go negative at a point between FET and the primary winding. A biasing capacitor is connected to apply an offset voltage which is additive to the feedback voltage so as to give a bias voltage to FET. The power supply is characterized to include a level detector which issues a zero voltage signal when the oscillation voltage is detected to lower to at least zero level, and to include a pulse generator which, in response to the zero voltage signal, produces a pulse of a predetermined pulse-width which overrides the feedback voltage in such a manner as to enable FET to turn on for a ON-period determined by the pulse-width only after the oscillation voltage is lowered to at least zero level, whereby avoiding FET from flowing a current while the oscillation voltage is still positive and therefore reducing a switching loss.

摘要： An inverter voltage source supplied from a DC source (10) comprises a FET switching element (31) and a transformer (20) with primary (21) and feedback winding (23). The primary (21) and capacitor (25) form a parallel resonant circuit which when resonating energises the load (27) via the secondary (22). A starter circuit (11, 12) across the source (10) provides an initial offset voltage (VB) at the FET (31) gate which switches on to commence a self-excited oscillation in the resonant circuit (21, 25) maintained by the feedback winding (23) and voltage (VG). A null-point detector (60) which triggers a pulse generator (50) employing pulse-width control ensures that the conducting periods of the FET (31) are optimally timed to minimise switching losses. ADVANTAGE - Largely eliminates switching losses of similar FET controlled systems resulting in improved efficiency and stability.

摘要： By applying to a coil an excitation AC signal biased by a predetermined DC voltage, failure information relating to, for example, disconnection or semi-disconnection of the coil is included in the DC voltage component of a coil output signal. The DC voltage component included in the coil output signal is detected and generated as an offset voltage used for a failure diagnosis. To check a peak level of the excitation AC signal, the DC voltage corresponding to the peak level may also be included in the offset voltage. In a differential amplifier circuit for obtaining the difference between a coil detection output AC voltage component and a reference AC voltage component, an output is generated such that the obtained difference signal is offset by the offset voltage. The difference signal including the offset voltage as failure information is thus transmitted through one output line to a torque measurement circuit as a torque detection signal. The torque measurement circuit, while generating torque detection data on the basis of the transmitted difference signal, extracts the offset voltage and uses the extracted offset voltage for a failure diagnosis.
