摘要： A resonant circuit inverter with a rectifier, a DC link circuit and an inverter including controllable switches. The resonant circuit inverter has a first control means, with which the operating point (Ap) of the resonant circuit inverter determined by a phase angle between an output current (Iist) and a voltage (Uist) at the output of the resonant circuit inverter is controlled. The first control means determines frequency of the output current (Iist). The resonant circuit inverter has a phase detector for determining an actual phase angle as a function of a zero crossing of the output current (Iist). The resonant circuit inverter has means for detecting a zero crossing of the output current (Iist). For determining the actual phase angle, the difference (Ti−Tt) is determined from measured time (Ti) and a known dead time (Tt).

摘要： A method for automatic calibration of the power of electromagnetic oven includes the following steps: 1) selecting two current test values within a range of working current of the electromagnetic oven, making it operate in the case of the current test values and zero, detecting voltage values of current signals under the three operation states; calculating, by a CPU, a coefficient k and an intercept b according to a formula y(i)=k×i+b using the three sets of data, and storing them; 2) during operation, calculating, by the CPU, a current current signal i using a voltage value y(i) of the current current signal detected by the current detection and collection circuit and the coefficient k and intercept b, according to a formula i=1/k×y(i)−b/k, and in turn calculating a current power using the current current signal and a current voltage signal. A calibration program is built in the chip for setting a parameter and automatically colleting and calculating the calibration parameter; during operation, the current or power may be automatically calibrated, which provides an accurate basis for adjusting the power of electromagnetic oven. The mode in which a conventional potentiometer is adopted for calibration may be replaced by the present invention, which results in reduction of cost and improvement of the reliability.

摘要： An inductive thermal bonding system includes at least one inductive bonding or heating member containing a magnetic E-shaped inductive core and a coil bounding a central member of the E-shaped inductive core. A rigid cover plate allows high and predictable temperature rate-of-change during use and reduced thermal cycling time without risk of detriment. Adaptive solid copper pads on multiplayer bonding regions minimize bonding errors and improve reliability. A cooling system is provided for adaptively cooling both the bond head and the bonded stack. Single and paired inductive heating members may be employed, and may also be alternatively controlled and positioned to aid generation of multiplayer bonding subassemblies distant from an edge of a multiplayer sheet construct.
