Figure 1(a) shows the schematic of proposed stubs loaded anti-parallel
coupled-line with short-circuited port 4 and port 3 terminated by the load ZL.
Those measured results include only the fundamental and the third harmonic components, while the second harmonic component cannot be detected because the even harmonic components circulate within the loop formed by the two anti-paralleled
For medium-sized drives an anti-parallel
arrangement is cheaper, mainly because there is no requirement for an anti-parallel
field convertor and associated controls.
As can be seen in Figure 1 each bridge arm is composed of four anti-parallel
diodes [S.sub.xy] (x = a,b,c; y = 1,2, 3,4) and two clamping diodes [D.sub.xy] (x = a, b, c; y = 1, 2), respectively.
The half-bridge VS-GP100TS60SFPBF, VS-GP300TD60S, and VS-GP400TD60S combine Trench PT IGBTs with HEXFRED and FRED Pt anti-parallel
diodes in the INT-A-PAK package and dual INT-A-PAK package with an extremely low profile of 17 mm.
Scores of police officers, including police chiefs, have been detained in what the pro-government calls "anti-parallel
structure" operationssince a corruption scandal erupted on Dec.
[D.sub.S1] and [D.sub.S2] are the anti-parallel
diodes of [S.sub.1] and [S.sub.2], respectively.
Two diodes are anti-parallel
arranged in the x direction in each unit cell.
In order to suppress the spurious passbands, many methods has been presented such as methods using the stepped-impedance resonators and grounded-step-impedance resonators [11, 18, 20, 23, 25, 26], fractal-shaped micro-strip , multi-order resonator , T-stub/DGS , antisymmetric modied anti-parallel
coupled-lines [15, 19, 21], branch stubs co-via structure , DGS and Spur-line Coupling Structures , etc..
The most popular power sources used for supplying ESP sections are those which are supplied from two phases, with two thyristors connected as anti-parallel
which, by controlling the ignition angle, modify the effective voltage in the transformer's bootstrap primary and directly the voltage on the ESP's section.
The series were compared with use of either procedure A (parallel) and B (anti-parallel
Inside the current monitor is a pair of amplifiers connected in anti-parallel
